Description

Technical Field

[0001] This invention relates to the field of compressed air energy storage artificial chamber technology, and in particular to a method, apparatus, medium and equipment for the general selection and survey of compressed air energy storage artificial chambers. Background Technology

[0002] Compressed air energy storage (CASS) is an important technology suitable for large-scale, long-term energy storage, playing a positive role in improving the peak-shaving capacity of the power system, promoting the consumption of new energy sources, and enhancing energy security. Artificial chamber CASS projects typically utilize underground rock space to construct gas storage caverns, and the site conditions have a significant impact on the project's construction and operation. Site selection not only relates to the stability, sealing, and construction feasibility of the underground cavern, but also affects surface site layout, grid connection, transportation, environmental coordination, project investment, and operational safety.

[0003] Currently, the selection of artificial compressed air energy storage (CASS) sites typically combines regional geological data analysis, engineering experience assessment, and multi-factor comparison. During the site selection process, factors such as topography, engineering geology, hydrogeology, transportation conditions, and external constraints are generally considered. While these methods have a certain foundation in engineering practice, the increasing demands for precision and standardization in CASS site selection reveal room for further optimization in certain application scenarios. For example, the evaluation index system, evaluation standards, and weighting settings among different candidate sites are sometimes inconsistent, affecting horizontal comparisons. Some site selection work focuses primarily on regional data screening, neglecting the independence, differences, and homogeneity of candidate sites, potentially impacting the representativeness of subsequent comparisons. Furthermore, discrepancies sometimes exist between regional data and actual site conditions; relying solely on preliminary data may fail to identify factors significantly impacting project layout and construction conditions. In addition, a systematic approach integrating site surveys, rejection factor identification, review scoring, and risk comparison still requires further refinement.

[0004] Therefore, it is necessary to propose a general selection and site survey method applicable to compressed air energy storage artificial chamber projects, so as to establish a phased, quantifiable and comparable site selection process. Summary of the Invention

[0005] In view of this, the present invention provides a method, apparatus, medium and equipment for the preliminary screening and reconnaissance of compressed air energy storage artificial chambers. It can achieve preliminary screening of candidate sites within the target site selection area, further determine representative sites through independence verification, and form a site ranking result by combining on-site investigation, veto item identification, review scoring and risk comparison, thereby providing support for subsequent survey design and engineering decision-making, and thus being more suitable for practical use.

[0006] To achieve the first objective mentioned above, the technical solution of the method for general selection and reconnaissance of compressed air energy storage artificial chambers provided by the present invention is as follows: The method for general selection and reconnaissance of compressed air energy storage artificial chambers provided by this invention includes the following steps: S1: For the existing target site selection areas, establish a first-stage quantitative evaluation index system. Based on the reservoir scale suitability conditions, topographic and geomorphological conditions, regional engineering geological conditions, regional hydrogeological conditions, external transportation conditions, infrastructure and population distribution constraints, and the relationship of ground site layout, quantitatively evaluate and screen the target site selection areas to obtain candidate reservoir sites. S2: Perform independence verification on candidate sites. The independence verification includes at least the verification of differences in geological units, differences in traffic organization, differences in external constraints, and synergy of ground sites, and determine the general selection site accordingly. S3: Based on the results of the on-site survey of the proposed reservoir site, obtain actual data on engineering geology, hydrogeology, topographic depth, tunnel layout, transportation, power grid connection, construction organization and environmental coordination related to reservoir construction, compare and correct existing data, and form a corresponding list of on-site issues; S4: Based on the site survey results and the list of on-site issues, identify the on-site veto items for each general election site and eliminate general election sites with significant unfavorable control factors; S5: Establish a second-stage review and scoring system for the general selection sites identified through on-site veto items. The review and scoring system and risk comparison are based on engineering geological conditions, hydrogeological conditions, topographic burial depth and cavern layout conditions, planning and environmental coordination, power system access conditions, transportation conditions, construction organization conditions and comprehensive risk level. S6: Based on the second-stage review and scoring results and risk comparison results, sort the general election sites identified through on-site veto items and output at least 2 comparison sites.

[0007] The method for general selection and reconnaissance of compressed air energy storage artificial chambers provided by the present invention can be further implemented by the following technical measures.

[0008] As a preferred option, in step S1, the first-stage quantitative evaluation index system adopts a combination of graded scoring and weighted summation for evaluation; each evaluation index is scored according to the preset level corresponding to the score value, and the first-stage comprehensive score is calculated in combination with the weight corresponding to each evaluation index.

[0009] Preferably, in step S1, the preset level includes at least five levels: excellent, good, medium, poor, and very poor, with the score values ​​corresponding to the five levels decreasing sequentially. When the comprehensive score of the first stage meets the preset score threshold, and at least one or more of the key indicators among the reservoir scale adaptation conditions, regional engineering geological conditions, and regional hydrogeological conditions meet the corresponding minimum admission requirements, the candidate reservoir site proceeds to step S2.

[0010] Preferably, in step S2, the independence verification includes: identifying the differences in the engineering geological units to which the candidate sites belong, the differences in external traffic organization conditions, the differences in the distribution of environmentally sensitive targets and infrastructure conflict conditions, the differences in surrounding constraints, and the differences in the surface site layout conditions and the coordination conditions between the underground cavern project; and based on the above-mentioned differences identification results, priority is given to retaining candidate sites belonging to different engineering geological units, with different traffic organization conditions and non-overlapping or low-overlapping external constraints as general selection sites.

[0011] Preferably, in step S3, the site survey includes on-site engineering geological survey, on-site hydrogeological survey, topographic depth and tunnel entrance condition survey, transportation survey, power grid access survey, and construction organization and environmental coordination survey; through the site survey, actual data related to the reservoir construction are obtained, and the actual data is compared and analyzed with existing data, the existing data is corrected, and a corresponding on-site problem list is formed.

[0012] Preferably, in step S4, the on-site rejection criteria include one or more of the following: geological stability does not meet the reservoir construction requirements, hydrogeological conditions do not meet the sealed reservoir construction requirements, topographic burial depth or cavern layout conditions do not meet the construction requirements, surface site and underground cavern coordination conditions do not meet the requirements, external transportation or power grid access conditions do not meet the requirements, construction organization conditions do not meet the requirements, and environmental coordination conditions do not meet the requirements. When any of the selected reservoir sites meets the preset rejection criteria, the selected reservoir site is eliminated.

[0013] As a preferred option, in step S5, the second-stage review scoring system is established by combining itemized quantification, itemized scoring, and comprehensive weighted scoring. In addition to forming a comprehensive score, the second-stage review scoring also forms key item scores for engineering geological conditions, hydrogeological conditions, and topographic burial depth and cavern layout conditions. The comprehensive score and key item scores are used together as the basis for ranking the reservoir sites.

[0014] Preferably, in step S5, the risk comparison includes at least a comparison of geological stability risk, groundwater leakage risk, construction organization risk, external coordination risk, and operational safety risk; the risk comparison forms a comprehensive risk level by classifying and evaluating each risk, and the comprehensive risk level and the second-stage review score are used together for site selection and ranking.

[0015] As a preferred option, in step S6, the general election sites identified through on-site veto items are initially sorted from high to low according to the comprehensive score of the second stage; when the comprehensive scores of different general election sites are the same or close, the general election sites with higher scores in key sub-items and lower comprehensive risk levels are selected first; finally, no less than 2 comparison sites are output.

Based on the adaptability of reservoir scale, topographic and geomorphological conditions, regional engineering geological conditions, regional hydrogeological conditions, external transportation conditions, infrastructure and population distribution constraints, and the relationship of ground site layout, the module quantitatively evaluates and screens the target site selection areas to obtain candidate sites. The general selection site determination module is used to perform independence verification on candidate sites. The independence verification includes at least the verification of differences in geological units, differences in traffic organization, differences in external constraints, and synergy of ground sites, and determines the general selection site accordingly. The on-site problem list generation module is used to obtain actual data on engineering geology, hydrogeology, topographic depth, tunnel layout, transportation, power grid connection, construction organization and environmental coordination related to reservoir construction based on the results of on-site surveys of the selected reservoir sites. It compares and corrects existing data and generates a corresponding on-site problem list. The veto item identification module is used to identify veto items for each general election site based on the site survey results and the list of on-site issues, and to eliminate general election sites with significant unfavorable control factors; The review scoring and risk comparison module is used to establish a second-stage review scoring system for the general selection sites identified through on-site veto items. The review scoring and risk comparison are based on engineering geological conditions, hydrogeological conditions, topographic burial depth and cavern layout conditions, planning and environmental coordination, power system access conditions, transportation conditions, construction organization conditions and comprehensive risk level. The comparison site output module is used to sort the general selection sites identified through on-site veto items based on the second-stage review scoring results and risk comparison results, and output at least two comparison sites.

[0017] To achieve the third objective mentioned above, the technical solution of the computer-readable storage medium provided by the present invention is as follows: The computer-readable storage medium provided by the present invention stores a program for the general selection and reconnaissance of compressed air energy storage artificial chambers.

Detailed Implementation

[0021] To address the problems existing in the prior art, this invention provides a method, apparatus, medium, and equipment for the preliminary screening and reconnaissance of compressed air energy storage artificial chambers. It can achieve preliminary screening of candidate sites within the target site selection area, further determine representative sites through independence verification, and form a site ranking result by combining on-site investigation, veto item identification, review scoring, and risk comparison, thereby providing support for subsequent survey design and engineering decision-making, and thus being more suitable for practical use.

[0022] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation methods, structures, features, and effects of the compressed air energy storage artificial chamber selection and survey method, apparatus, medium, and equipment proposed according to the present invention. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0023] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can mean that A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0024] Methods for the general selection and site survey of artificial chambers for compressed air energy storage See appendix Figure 1 The method for general selection and reconnaissance of compressed air energy storage artificial chambers provided in this embodiment of the invention includes the following steps: S1: For the existing target site selection areas, establish a first-stage quantitative evaluation index system. Based on the reservoir scale suitability conditions, topographic and geomorphological conditions, regional engineering geological conditions, regional hydrogeological conditions, external transportation conditions, infrastructure and population distribution constraints, and the relationship of ground site layout, quantitatively evaluate and screen the target site selection areas to obtain candidate reservoir sites. The aforementioned reservoir scale adaptation conditions are used to evaluate the adaptability of the underground space corresponding to the candidate reservoir site to the requirements of target gas storage scale, number of caverns, cavern length, and cavern spacing; the aforementioned topographic and geomorphological conditions are used to evaluate the continuity of the mountain, slope conditions, topographic integrity, and ease of engineering deployment; the aforementioned regional engineering geological conditions are used to evaluate the development of fault structures, lithological combinations, rock mass integrity, and regional stability; the aforementioned regional hydrogeological conditions are used to evaluate the characteristics of groundwater recharge, runoff, discharge, water abundance, and permeability; the aforementioned external transportation conditions are used to evaluate the connection conditions of existing transportation arteries, the conditions of heavy-duty transportation channels, and the ease of traffic organization; the aforementioned infrastructure and population distribution constraints are used to evaluate the relationship between the candidate reservoir site and residential areas, important facilities, sensitive areas, and control areas; the aforementioned surface site layout relationship is used to evaluate the coordinated layout conditions between the underground cavern and surface compression stations, substations, construction sites, and ancillary facilities.

[0025] The first-stage quantitative evaluation index system employs a combination of tiered scoring and weighted summation. Specifically, each evaluation indicator has a pre-set grade of at least five levels: Excellent, Good, Average, Poor, and Very Poor, with corresponding score values ​​decreasing sequentially. The score value of each indicator is multiplied by its corresponding weight and then summed to obtain the overall score for the first stage.

[0026] The weights can be determined based on engineering experience, expert scoring, analytic hierarchy process (AHP), or other conventional methods. To highlight the core reservoir construction conditions, higher weights can be assigned to reservoir scale suitability conditions, regional engineering geological conditions, and regional hydrogeological conditions.

[0027] Within the target site selection area, candidate reservoir sites that meet the preset score threshold in the first stage and whose key indicators among reservoir scale suitability, regional engineering geological conditions, and regional hydrogeological conditions meet the corresponding minimum admission requirements are screened, and the screened candidate reservoir sites are included in step S2. The preset score threshold can be set according to project needs, for example, it can be set to 70 points or other suitable values.

[0028] After step S1 is completed, the target site selection area first-stage scoring table, the scoring basis of each indicator, the first-stage comprehensive score ranking table, and the candidate site list for step S2 can be generated.

[0029] S2: Perform independence verification on candidate sites. The independence verification includes at least the verification of differences in geological units, differences in traffic organization, differences in external constraints, and synergy of ground sites, and determine the general selection site accordingly. Specifically, the geological unit differences are used to identify whether candidate sites are located in different engineering geological units, and whether there are significant differences in their fracture structures, lithological combinations, rock mass integrity, and overall stability characteristics; the traffic organization differences are used to identify whether there are differences in the access road systems, heavy equipment transportation routes, and traffic organization methods among candidate sites; the external constraint condition differences are used to identify whether the distribution of environmentally sensitive targets, infrastructure conflicts, and surrounding control constraints overlap or are similar; and the surface site synergy is used to identify whether there are significant differences in the degree of synergy between the surface engineering layout and the underground cavern layout.

[0030] An independent comparison relationship is established for each candidate reservoir site, and pairwise comparisons are performed between the candidate reservoir sites. If multiple candidate reservoir sites are located in the same engineering geological unit, share the same transportation corridor, are subject to the same external constraints, and have similar coordination conditions between the surface site and the underground reservoir, then these candidate reservoir sites are considered to have a high degree of homogeneity.

[0031] For candidate sites with a high degree of homogeneity, priority will be given to retaining those with higher comprehensive scores in the first stage, better key construction conditions, fewer external constraints, and more reasonable ground site coordination. Candidate sites belonging to different engineering geological units, with different traffic organization conditions, and with non-overlapping or low-overlapping external constraints will be retained as general selection sites.

[0032] The number of general election sites can be determined based on the project scale and the depth of subsequent screening, but generally no less than three, to ensure that subsequent on-site investigations and comprehensive screenings have a sufficient basis for comparison.

[0033] After step S2 is completed, an independence verification comparison table, a description of the homogeneity analysis of candidate sites, and the results of the general selection of sites can be generated.

[0034] S3: Conduct on-site surveys of the selected reservoir sites to obtain actual data related to reservoir construction, including engineering geology, hydrogeology, topographic depth, tunnel layout, transportation, power grid connection, construction organization, and environmental coordination. Compare and revise existing data, and form a corresponding list of on-site issues. The site survey includes on-site engineering geological survey, on-site hydrogeological survey, topographic depth and tunnel entrance condition survey, transportation survey, power grid access survey, and construction organization and environmental coordination survey.

[0035] The on-site engineering geological reconnaissance is used to identify faults, joints, fracture zones, unfavorable geological bodies, weathering characteristics, and rock mass integrity. The on-site hydrogeological reconnaissance is used to identify groundwater recharge, runoff, discharge conditions, water-rich characteristics, and sensitive seepage locations. The topographic depth and tunnel entrance condition reconnaissance is used to identify mountain thickness, overburden thickness, tunnel entrance elevation, tunnel entrance development conditions, and tunnel depth conditions. The transportation reconnaissance is used to identify access roads, large equipment transportation channels, bridge and culvert capacity, and transportation organization conditions. The power grid connection reconnaissance is used to identify connection distance, connection conditions, and related supporting construction conditions. The construction organization and environmental coordination reconnaissance is used to identify construction site layout, waste disposal conditions, material storage conditions, distribution of surrounding sensitive points, and environmental coordination conditions.

[0036] After obtaining relevant data through the on-site survey, the actual data is compared and analyzed item by item with existing data, and any deviations, omissions, or insufficient applicability in the existing data are corrected. The existing data includes, but is not limited to, preliminary geological data, hydrogeological data, topographic data, transportation data, power grid data, and environmental data.

[0037] A list of on-site issues will be compiled for each general election site. The on-site issue list shall include at least the issue number, issue location, issue category, issue description, possible engineering aspects that may be affected, preliminary assessment level, and recommended handling opinions.

[0038] After step S3 is completed, a site survey record form, site photos and video data, data correction comparison table, and a list of on-site issues for each general election site can be generated.

[0039] S4: Based on the site survey results and the list of on-site issues, identify the on-site veto items for each general election site and eliminate general election sites with significant unfavorable control factors; The on-site rejection items include one or more of the following: geological stability does not meet the requirements for reservoir construction; hydrogeological conditions do not meet the requirements for sealed reservoir construction; topographic burial depth or cavern layout conditions do not meet the construction requirements; surface site and underground cavern coordination conditions do not meet the requirements; external transportation or power grid access conditions do not meet the requirements; construction organization conditions do not meet the requirements; and environmental coordination conditions do not meet the requirements.

[0040] Among the reasons for insufficient geological stability to meet reservoir construction requirements, the following issues may apply: controllable fault cutting, development of strong fracture zones, significant overall instability, or significant deviation in rock mass integrity. Insufficient hydrogeological conditions to meet sealed reservoir construction requirements may include abnormally rich groundwater, developed seepage channels, or conditions clearly unfavorable to sealed reservoir construction. Insufficient topographic depth or cavern layout conditions may include insufficient effective mountain thickness, insufficient cavern depth, or significantly limited cavern development space. Insufficient coordination between the surface site and underground cavern may include difficulties in the layout of the surface station area, difficulties in cavern development, or difficulty in coordinating above-ground and underground engineering. Insufficient external transportation or power grid access conditions may include difficulties in organizing large-scale transportation or excessive difficulty in implementing power grid access. Insufficient construction organization conditions may include inadequate construction site conditions, waste disposal conditions, or significant deficiencies in construction organization. Insufficient environmental coordination conditions may include significant conflicts with environmentally sensitive targets, important infrastructure, or other controlled protected objects.

[0041] For each general election site, the results of the on-site inspection and the list of on-site issues are used to determine whether a preset veto criterion is triggered. If any general election site meets any preset veto criterion, the site will be removed from the subsequent second-stage review and scoring.

[0042] After step S4 is completed, an on-site veto item identification table, a conclusion on whether to retain or remove each general election site, and a list of retained sites to proceed to step S5 can be generated.

[0043] S5: Establish a second-stage review and scoring system for the general selection sites identified through on-site veto items. The review and scoring system and risk comparison are based on engineering geological conditions, hydrogeological conditions, topographic burial depth and cavern layout conditions, planning and environmental coordination, power system access conditions, transportation conditions, construction organization conditions and comprehensive risk level. The second-stage review scoring system was established using a combination of itemized quantification, itemized scoring, and comprehensive weighted scoring. Each reserved reservoir site was scored based on engineering geological conditions, hydrogeological conditions, topographic burial depth and cavern layout conditions, planning and environmental compatibility, power system access conditions, transportation conditions, and construction organization conditions, and the comprehensive score for the second stage was calculated based on the corresponding weights.

[0044] In addition to the overall score, this embodiment also generates key sub-scores for engineering geological conditions, hydrogeological conditions, and topographic burial depth and cavern layout conditions, which serve as key references when ranking reservoir sites. By setting key sub-scores, it is possible to avoid situations where high scores for auxiliary conditions mask deficiencies in core reservoir construction conditions.

[0045] The risk comparison includes at least geological stability risk, groundwater leakage risk, construction organization risk, external coordination risk, and operational safety risk. A tiered evaluation method can be used to classify each risk and form a comprehensive risk level.

[0046] Among them, geological stability risk mainly reflects the impact of surrounding rock stability and structural complexity on the safety of project implementation and operation; groundwater leakage risk mainly reflects the impact of water abundance, permeability and difficulty in sealing the reservoir on the sealing effect of the cavern; construction organization risk mainly reflects the difficulty of construction traffic, construction site, waste disposal and organization; external coordination risk mainly reflects the difficulty of coordination with planning, environment, surrounding sensitive targets and external facilities; and operation safety risk mainly reflects the stability, sealing and external impact risks that may exist in the operation phase after completion.

[0047] The second-stage review score and the comprehensive risk level are used together for site selection and ranking. Preferably, the second-stage comprehensive score and the comprehensive risk level can be combined to form a two-factor evaluation result to improve the rationality of the site ranking.

[0048] After step S5 is completed, the second-stage review scoring table, key sub-item scoring table, risk comparison table for each site, and second-stage comprehensive evaluation description can be generated.

[0049] S6: Based on the second-stage review and scoring results and risk comparison results, sort the general selection sites identified through on-site veto items and output at least 2 comparison sites; First, preliminary ranking is conducted based on the overall scores from highest to lowest in the second stage. When the overall scores of different general election sites are the same or close, priority is given to general election sites with higher scores in key sub-items and lower overall risk levels.

[0050] Among them, the higher scores of the key sub-items refer to the superior core reservoir construction conditions such as engineering geological conditions, hydrogeological conditions, and topographic burial depth and cavern layout conditions; the lower comprehensive risk level refers to the more controllable overall risks in terms of geology, hydrology, construction, coordination and operational safety.

[0051] The final output should include no fewer than two alternative storage sites, along with a ranking table of the alternative sites, an analysis of their advantages and disadvantages, and suggestions for future work.

[0052] The compressed air energy storage artificial chamber selection and reconnaissance method provided by this invention can achieve preliminary screening of candidate sites within the target site selection area, further determine representative sites through independence verification, and form a site ranking result by combining on-site investigation, veto item identification, review scoring and risk comparison, thereby providing support for subsequent survey design and engineering decision-making.

Based on the adaptability of reservoir scale, topographic and geomorphological conditions, regional engineering geological conditions, regional hydrogeological conditions, external transportation conditions, infrastructure and population distribution constraints, and the relationship of ground site layout, the module quantitatively evaluates and screens the target site selection areas to obtain candidate sites. The aforementioned reservoir scale adaptation conditions are used to evaluate the adaptability of the underground space corresponding to the candidate reservoir site to the requirements of target gas storage scale, number of caverns, cavern length, and cavern spacing; the aforementioned topographic and geomorphological conditions are used to evaluate the continuity of the mountain, slope conditions, topographic integrity, and ease of engineering deployment; the aforementioned regional engineering geological conditions are used to evaluate the development of fault structures, lithological combinations, rock mass integrity, and regional stability; the aforementioned regional hydrogeological conditions are used to evaluate the characteristics of groundwater recharge, runoff, discharge, water abundance, and permeability; the aforementioned external transportation conditions are used to evaluate the connection conditions of existing transportation arteries, the conditions of heavy-duty transportation channels, and the ease of traffic organization; the aforementioned infrastructure and population distribution constraints are used to evaluate the relationship between the candidate reservoir site and residential areas, important facilities, sensitive areas, and control areas; the aforementioned surface site layout relationship is used to evaluate the coordinated layout conditions between the underground cavern and surface compression stations, substations, construction sites, and ancillary facilities.

[0054] The first-stage quantitative evaluation index system employs a combination of tiered scoring and weighted summation. Specifically, each evaluation indicator has a pre-set grade of at least five levels: Excellent, Good, Average, Poor, and Very Poor, with corresponding score values ​​decreasing sequentially. The score value of each indicator is multiplied by its corresponding weight and then summed to obtain the overall score for the first stage.

[0055] The weights can be determined based on engineering experience, expert scoring, analytic hierarchy process (AHP), or other conventional methods. To highlight the core reservoir construction conditions, higher weights can be assigned to reservoir scale suitability conditions, regional engineering geological conditions, and regional hydrogeological conditions.

[0056] Within the target site selection area, candidate reservoir sites that meet the preset score threshold in the first stage and whose key indicators among reservoir scale suitability, regional engineering geological conditions, and regional hydrogeological conditions meet the corresponding minimum admission requirements are screened, and the screened candidate reservoir sites are included in step S2. The preset score threshold can be set according to project needs, for example, it can be set to 70 points or other suitable values.

[0057] After step S1 is completed, the target site selection area first-stage scoring table, the scoring basis of each indicator, the first-stage comprehensive score ranking table, and the candidate site list for step S2 can be generated.

[0058] The general selection site determination module is used to perform independence verification on candidate sites. The independence verification includes at least the verification of differences in geological units, differences in traffic organization, differences in external constraints, and synergy of ground sites, and determines the general selection site accordingly. Specifically, the geological unit differences are used to identify whether candidate sites are located in different engineering geological units, and whether there are significant differences in their fracture structures, lithological combinations, rock mass integrity, and overall stability characteristics; the traffic organization differences are used to identify whether there are differences in the access road systems, heavy equipment transportation routes, and traffic organization methods among candidate sites; the external constraint condition differences are used to identify whether the distribution of environmentally sensitive targets, infrastructure conflicts, and surrounding control constraints overlap or are similar; and the surface site synergy is used to identify whether there are significant differences in the degree of synergy between the surface engineering layout and the underground cavern layout.

[0059] An independent comparison relationship is established for each candidate reservoir site, and pairwise comparisons are performed between the candidate reservoir sites. If multiple candidate reservoir sites are located in the same engineering geological unit, share the same transportation corridor, are subject to the same external constraints, and have similar coordination conditions between the surface site and the underground reservoir, then these candidate reservoir sites are considered to have a high degree of homogeneity.

[0060] For candidate sites with a high degree of homogeneity, priority will be given to retaining those with higher comprehensive scores in the first stage, better key construction conditions, fewer external constraints, and more reasonable ground site coordination. Candidate sites belonging to different engineering geological units, with different traffic organization conditions, and with non-overlapping or low-overlapping external constraints will be retained as general selection sites.

[0061] The number of general election sites can be determined based on the project scale and the depth of subsequent screening, but generally no less than three, to ensure that subsequent on-site investigations and comprehensive screenings have a sufficient basis for comparison.

[0062] After step S2 is completed, an independence verification comparison table, a description of the homogeneity analysis of candidate sites, and the results of the general selection of sites can be generated.

[0063] The on-site problem list generation module is used to obtain actual data on engineering geology, hydrogeology, topographic depth, tunnel layout, transportation, power grid connection, construction organization and environmental coordination related to reservoir construction based on the results of on-site surveys of the selected reservoir sites. It compares and corrects existing data and generates a corresponding on-site problem list. The site survey includes on-site engineering geological survey, on-site hydrogeological survey, topographic depth and tunnel entrance condition survey, transportation survey, power grid access survey, and construction organization and environmental coordination survey.

[0064] The on-site engineering geological reconnaissance is used to identify faults, joints, fracture zones, unfavorable geological bodies, weathering characteristics, and rock mass integrity. The on-site hydrogeological reconnaissance is used to identify groundwater recharge, runoff, discharge conditions, water-rich characteristics, and sensitive seepage locations. The topographic depth and tunnel entrance condition reconnaissance is used to identify mountain thickness, overburden thickness, tunnel entrance elevation, tunnel entrance development conditions, and tunnel depth conditions. The transportation reconnaissance is used to identify access roads, large equipment transportation channels, bridge and culvert capacity, and transportation organization conditions. The power grid connection reconnaissance is used to identify connection distance, connection conditions, and related supporting construction conditions. The construction organization and environmental coordination reconnaissance is used to identify construction site layout, waste disposal conditions, material storage conditions, distribution of surrounding sensitive points, and environmental coordination conditions.

[0065] After obtaining relevant data through the on-site survey, the actual data is compared and analyzed item by item with existing data, and any deviations, omissions, or insufficient applicability in the existing data are corrected. The existing data includes, but is not limited to, preliminary geological data, hydrogeological data, topographic data, transportation data, power grid data, and environmental data.

[0066] A list of on-site issues will be compiled for each general election site. The on-site issue list shall include at least the issue number, issue location, issue category, issue description, possible engineering aspects that may be affected, preliminary assessment level, and recommended handling opinions.

[0067] After step S3 is completed, a site survey record form, site photos and video data, data correction comparison table, and a list of on-site issues for each general election site can be generated.

[0068] The veto item identification module is used to identify veto items for each general election site based on the site survey results and the list of on-site issues, and to eliminate general election sites with significant unfavorable control factors; The on-site rejection items include one or more of the following: geological stability does not meet the requirements for reservoir construction; hydrogeological conditions do not meet the requirements for sealed reservoir construction; topographic burial depth or cavern layout conditions do not meet the construction requirements; surface site and underground cavern coordination conditions do not meet the requirements; external transportation or power grid access conditions do not meet the requirements; construction organization conditions do not meet the requirements; and environmental coordination conditions do not meet the requirements.

[0069] Among the reasons for insufficient geological stability to meet reservoir construction requirements, the following issues may apply: controllable fault cutting, development of strong fracture zones, significant overall instability, or significant deviation in rock mass integrity. Insufficient hydrogeological conditions to meet sealed reservoir construction requirements may include abnormally rich groundwater, developed seepage channels, or conditions clearly unfavorable to sealed reservoir construction. Insufficient topographic depth or cavern layout conditions may include insufficient effective mountain thickness, insufficient cavern depth, or significantly limited cavern development space. Insufficient coordination between the surface site and underground cavern may include difficulties in the layout of the surface station area, difficulties in cavern development, or difficulty in coordinating above-ground and underground engineering. Insufficient external transportation or power grid access conditions may include difficulties in organizing large-scale transportation or excessive difficulty in implementing power grid access. Insufficient construction organization conditions may include inadequate construction site conditions, waste disposal conditions, or significant deficiencies in construction organization. Insufficient environmental coordination conditions may include significant conflicts with environmentally sensitive targets, important infrastructure, or other controlled protected objects.

[0070] For each general election site, the results of the on-site inspection and the list of on-site issues are used to determine whether a preset veto criterion is triggered. If any general election site meets any preset veto criterion, the site will be removed from the subsequent second-stage review and scoring.

[0071] After step S4 is completed, an on-site veto item identification table, a conclusion on whether to retain or remove each general election site, and a list of retained sites to proceed to step S5 can be generated.

[0072] The review scoring and risk comparison module is used to establish a second-stage review scoring system for the general selection sites identified through on-site veto items. The review scoring and risk comparison are based on engineering geological conditions, hydrogeological conditions, topographic burial depth and cavern layout conditions, planning and environmental coordination, power system access conditions, transportation conditions, construction organization conditions and comprehensive risk level. The second-stage review scoring system was established using a combination of itemized quantification, itemized scoring, and comprehensive weighted scoring. Each reserved reservoir site was scored based on engineering geological conditions, hydrogeological conditions, topographic burial depth and cavern layout conditions, planning and environmental compatibility, power system access conditions, transportation conditions, and construction organization conditions, and the comprehensive score for the second stage was calculated based on the corresponding weights.

[0073] In addition to the overall score, this embodiment also generates key sub-scores for engineering geological conditions, hydrogeological conditions, and topographic burial depth and cavern layout conditions, which serve as key references when ranking reservoir sites. By setting key sub-scores, it is possible to avoid situations where high scores for auxiliary conditions mask deficiencies in core reservoir construction conditions.

[0074] The risk comparison includes at least geological stability risk, groundwater leakage risk, construction organization risk, external coordination risk, and operational safety risk. A tiered evaluation method can be used to classify each risk and form a comprehensive risk level.

[0075] Among them, geological stability risk mainly reflects the impact of surrounding rock stability and structural complexity on the safety of project implementation and operation; groundwater leakage risk mainly reflects the impact of water abundance, permeability and difficulty in sealing the reservoir on the sealing effect of the cavern; construction organization risk mainly reflects the difficulty of construction traffic, construction site, waste disposal and organization; external coordination risk mainly reflects the difficulty of coordination with planning, environment, surrounding sensitive targets and external facilities; and operation safety risk mainly reflects the stability, sealing and external impact risks that may exist in the operation phase after completion.

[0076] The second-stage review score and the comprehensive risk level are used together for site selection and ranking. Preferably, the second-stage comprehensive score and the comprehensive risk level can be combined to form a two-factor evaluation result to improve the rationality of the site ranking.

[0077] After step S5 is completed, the second-stage review scoring table, key sub-item scoring table, risk comparison table for each site, and second-stage comprehensive evaluation description can be generated.

[0078] The comparison site output module is used to sort the general selection sites identified through on-site veto items based on the second-stage review scoring results and risk comparison results, and output at least two comparison sites. First, preliminary ranking is conducted based on the overall scores from highest to lowest in the second stage. When the overall scores of different general election sites are the same or close, priority is given to general election sites with higher scores in key sub-items and lower overall risk levels.

[0079] Among them, the higher scores of the key sub-items refer to the superior core reservoir construction conditions such as engineering geological conditions, hydrogeological conditions, and topographic burial depth and cavern layout conditions; the lower comprehensive risk level refers to the more controllable overall risks in terms of geology, hydrology, construction, coordination and operational safety.

[0080] The final output should include no fewer than two alternative storage sites, along with a ranking table of the alternative sites, an analysis of their advantages and disadvantages, and suggestions for future work.
