DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The present invention provides a groundwater environment assessment method for underground space development, such as Figure 1 As shown, the method includes: Step S1: obtaining geological information and water environment information of a target development area through a data collection unit, and creating a three-dimensional twin model of the target development area based on the geological information and the water environment information; Specifically, the geological information and the water environment information of the target development area are collected through the data collection unit, and preprocessed and fused based on the geological information and the water environment information. The three-dimensional twin model corresponding to the target development area is created based on the fused geological information and the water environment data, wherein the geological information includes the soil type at each position in the target development area and the permeability corresponding to each soil type, and the water environment information includes the distribution of water systems in the target development area and the water system path of each water system, the water flow velocity of each water system and the cross-sectional area at each position. Through the technical solution, the three-dimensional twin model that can reflect the geological characteristics and water system characteristics of the target development area is obtained, thereby providing a basis for simulating the construction site based on the development drawings.

[0017] Step S2: dividing the three-dimensional twin model into a plurality of sub-areas, simulating the construction site of each construction process based on the construction process of each sub-area and the three-dimensional twin model, and acquiring construction site data; Specifically, the construction process is obtained through the above-mentioned development design drawings and development plans, and the above-mentioned three-dimensional twin model is obtained according to the above-mentioned construction area corresponding to the above-mentioned construction process and divided into multiple sub-areas. Furthermore, according to the construction sequence of each of the above-mentioned construction processes, the construction process of the above-mentioned construction process is simulated in the above-mentioned sub-area corresponding to the corresponding three-dimensional twin model, so that the above-mentioned construction site data can be obtained more realistically. Through the above-mentioned technical scheme, the foundation is laid for further calculating the risk of damage to the water environment of the above-mentioned sub-area caused by the above-mentioned construction process.

[0018] Step S3: judging whether the construction site conflicts with the water system path in the sub-area based on the construction scope in the construction site data corresponding to the construction process, and in case of conflict, correcting the conflicting path to obtain a corrected path, comparing the corrected path with the conflicting path to obtain a comparison result, and obtaining a first risk score corresponding to the conflicting path according to the comparison result and a first evaluation standard; Specifically, by comparing the above-mentioned construction scope in the construction site data corresponding to the above-mentioned construction process with each water system path in the above-mentioned sub-water environment data corresponding to the above-mentioned sub-area, and obtaining the comparison result, it is judged whether the above-mentioned construction site conflicts with each of the above-mentioned water system paths according to the above-mentioned comparison result. When the above-mentioned comparison result shows that the above-mentioned construction scope and the above-mentioned water system path have an intersection, the construction site in the above-mentioned sub-area conflicts with the above-mentioned water system path, and the above-mentioned water system path is used as the first water system path. Otherwise, there is no conflict. When the above-mentioned conflict exists, in order to ensure the smooth progress of the above-mentioned construction process, the conflicting path needs to be located. The water system section is dredged to obtain a correction path, and the water system characteristics corresponding to the above correction path are compared with the water system characteristics corresponding to the above conflicting path to obtain the difference between the two, that is, the above comparison result. The above water system characteristics include hydrodynamic field, water level and flow velocity. The above first risk score is obtained according to the above difference and the first evaluation standard, wherein the above first evaluation standard is a scoring rule for evaluating the degree of change of the hydrodynamic field, water level and flow velocity. Through the above technical solution, the first risk score corresponding to each conflicting path in each of the above sub-areas can be obtained, laying a foundation for obtaining the water environment risk score of the above target development area.

[0019] Step S4: When the construction site data corresponding to the construction process in the sub-area does not conflict with the water system in the sub-area, the harmful substance information in the construction process is also obtained based on the construction site data, and the target water system and target water system information are obtained based on the harmful substance information and the sub-environment information corresponding to the sub-area. The pollution information of the sub-area is predicted based on the target water system information, the harmful substance information, the soil permeability between the polluted section of the target water system and the harmful substance pollution source, and the pollution prediction sub-model corresponding to the sub-area in the pollution prediction model.

[0020] Specifically, when the construction site in the sub-area does not conflict with the water system path corresponding to the sub-water environment information, the water system path is used as the second water system path, and the harmful substance information is obtained according to the construction site data. The shortest distance between the pollution source position of the harmful substance in the harmful substance information and each of the second water system paths is calculated, and the water system corresponding to the second water system path whose shortest distance is less than the first set distance is used as the target water system. The water system path section of the target water system whose distance from the pollution source position is less than the second set distance is used as the polluted section. The pollution area corresponding to the target water system is obtained through the sub-environmental information. The water flow velocity and water flow cross-sectional area of ​​the segment are obtained, and the soil permeability between the above-mentioned pollution source and the above-mentioned polluted section is obtained through the sub-geological information corresponding to the above-mentioned sub-region. By inputting the water flow velocity and cross-sectional area of ​​the above-mentioned polluted section and other sections, the above-mentioned harmful substance concentration, the distance between the location of the above-mentioned pollution source and the above-mentioned polluted section, and the soil permeability between the above-mentioned pollution source and the above-mentioned polluted section into the pollution prediction sub-model corresponding to the above-mentioned sub-region in the above-mentioned pollution prediction model, the pollution scope and pollution degree caused by the above-mentioned pollution source to the above-mentioned target water system that changes with time are obtained. Through the above-mentioned technical scheme, the pollution scope and pollution degree of each pollution source in each sub-region to the corresponding target water system that changes with time can be accurately obtained.

[0021] Furthermore, a second risk score for each sub-area is obtained based on all pollution information of each sub-area and the pollution information of adjacent sub-areas, and a water environment risk assessment result for the target development area is obtained based on the first risk score and the second risk score of each sub-area.

[0022] Specifically, since there are multiple sub-areas with different construction processes being carried out simultaneously in the target development area, and since the water systems in adjacent sub-areas intersect, it is possible that the pollution ranges in multiple adjacent sub-areas may overlap over time. Therefore, all pollution information corresponding to all pollution sources in the sub-areas is obtained, and it is determined whether the pollution range in the pollution information corresponding to each pollution source in the sub-area intersects with the pollution range in the pollution information corresponding to each pollution source in the adjacent sub-area. When the two do not intersect, the second risk score of the sub-area is obtained based on the above-mentioned all pollution information in the sub-area and the above-mentioned second scoring standard. If the two intersect and the intersection position is located in the sub-area, the second risk score of the sub-area is obtained. domain, the pollution information at the intersection position is added to the total pollution information of the above sub-area to obtain the total pollution information, and the second risk score corresponding to the above sub-area is obtained according to the above total pollution information and the above second scoring standard, the above first risk score and the above second risk score corresponding to the above sub-area are used as the sub-risk assessment result of the above sub-area, and the risk level of the average value of the sub-risk assessment results in all the above sub-areas is used as the water environment assessment result of the above target development area, and the above risk level is obtained according to the risk level classification standard. Through the above technical scheme, the risk level of the above target development area that changes with time can be accurately obtained, which is convenient for users to take timely measures to prevent pollution from worsening during construction.

[0023] Further, obtaining the construction site data includes: Acquire a construction process according to the development design drawings and development plan of the target development area, and divide the three-dimensional twin model corresponding to the target development area into a plurality of sub-areas based on the construction areas corresponding to the construction process; The construction site is simulated in the three-dimensional twin model according to the construction process corresponding to the construction procedure in the sub-area, and the construction site data is acquired. The construction site data includes the construction scope and the sub-geological data and sub-water environment data within the construction scope.

[0024] Specifically, the construction process is obtained through the above-mentioned development design drawings and development plans, that is, the above-mentioned development design drawings can obtain the development content of the above-mentioned target development area, and the above-mentioned specific construction process is obtained based on the above-mentioned development content and the above-mentioned development plan, and the above-mentioned three-dimensional twin model is obtained according to the above-mentioned construction area corresponding to the above-mentioned construction process and divided into multiple above-mentioned sub-areas, wherein the above-mentioned construction process includes not only sequential execution but also parallel execution, and according to the construction sequence of each of the above-mentioned construction process, the construction process of the above-mentioned construction process is simulated in the above-mentioned sub-area corresponding to the corresponding three-dimensional twin model, so that the above-mentioned construction site data can be truly obtained, and the above-mentioned technical scheme can lay the foundation for further calculating the risk of damage caused by the above-mentioned construction process to the water environment corresponding to the above-mentioned sub-area.

[0025] Further, judging whether the water system path in the water environment information of the construction site conflicts with that in the sub-area includes: Compare the construction scope in the construction site data corresponding to the construction process in the sub-area with each water system path in the sub-water environment information corresponding to the sub-area; when the construction scope intersects with any of the water system paths, the construction site conflicts with the water system path in the sub-water environment, and the water system path serves as the first water system path; otherwise, there is no conflict; Calculating the first risk score of the conflict path includes: Based on the intersection of the construction site and each of the first water system paths, the conflict path and the position of the conflict path are obtained, the conflict path is corrected according to the position and the safety distance of the conflict path to obtain the corrected path, and the water system characteristics corresponding to the corrected path are simulated in the three-dimensional twin model, and the water system characteristics of the conflict path are compared with the water system characteristics of the corrected path to obtain a comparison result, and a first risk score is obtained according to the comparison result and the first evaluation standard.

[0026] Specifically, by comparing the above-mentioned construction scope in the construction site data corresponding to the above-mentioned construction process with each water system path in the above-mentioned sub-water environment data corresponding to the above-mentioned sub-area, and obtaining the comparison result, it is judged whether the above-mentioned construction site conflicts with each of the above-mentioned water system paths according to the above-mentioned comparison result. When the above-mentioned comparison result shows that the above-mentioned construction scope and the above-mentioned water system path have an intersection, the construction site in the above-mentioned sub-area conflicts with the above-mentioned water system path, and the above-mentioned water system path is used as the first water system path. Otherwise, there is no conflict. When the above-mentioned conflict exists, in order to ensure the smooth progress of the above-mentioned construction process, it is necessary to dredge the water system section where the above-mentioned conflicting path is located. Therefore, the position of the water system section that needs to be dredged is determined according to the position of the above-mentioned conflicting path and the above-mentioned construction scope. When dredging the water system section where the above-mentioned conflicting path is located, it is necessary to comply with the minimum limit. Under the premise of changing the hydrodynamic field, flow velocity and water level of the water system section where the above-mentioned conflicting path is located, a predetermined safety distance needs to be maintained between the above-mentioned construction range and the above-mentioned correction path to prevent the above-mentioned construction process from causing pollution to the water system section where the correction path is located during the construction process, and the water system characteristics corresponding to the above-mentioned correction path are compared with the water system characteristics corresponding to the above-mentioned conflicting path to obtain the difference between the two, that is, the above-mentioned comparison result. The above-mentioned water system characteristics include hydrodynamic field, water level and flow velocity. The above-mentioned first risk score is obtained according to the above-mentioned difference and the first evaluation standard, wherein the above-mentioned first evaluation standard is a scoring rule for evaluating the degree of change of hydrodynamic field, water level and flow velocity. Through the above-mentioned technical scheme, the first risk score corresponding to each conflicting path in each of the above-mentioned sub-areas can be obtained, laying a foundation for obtaining the water environment risk score of the above-mentioned target development area.

[0027] Furthermore, when the construction site in the sub-area does not conflict with the water system path in the corresponding sub-water environment information, the water system path is used as the second water system path, and harmful substance information is obtained according to the construction site data, the harmful substance information includes the type and concentration of the harmful substance and the pollution source and the pollution source location of the harmful substance, and the shortest distance between the pollution source location and each of the second water system paths is calculated based on the pollution source location and the second water system path, and the water system corresponding to the second water system path whose shortest distance is less than the first set distance is used as the target water system, and each of the sub-environment data The water flow velocity and water flow cross-sectional area of ​​the polluted section corresponding to the target water system are used as the target water system information, and the water flow velocity and water flow cross-sectional area of ​​the polluted section and other sections of the target water system, the concentration of the harmful substances, the distance between the pollution source and the polluted section of the target water system, and the soil permeability between the pollution source and the polluted section are input into the pollution prediction sub-model corresponding to the sub-area in the pollution prediction model to obtain the pollution range and pollution degree of the target water system that changes with time, and the pollution range, pollution degree and corresponding time that change with time are used as the pollution information; Among them, the polluted section is a water system path section corresponding to the target water system where the distance between the water system path of the target water system and the pollution source location is less than a second set distance.

[0028] Specifically, when the construction site in the sub-area does not conflict with the water system path corresponding to the sub-water environment information, the water system path is taken as the second water system path, that is, the construction range corresponding to the construction site has no intersection with the second water system path. Although the second water system path does not conflict with the construction range, it may be contaminated by infiltration. Therefore, the harmful substance information is obtained according to the construction site data, and the shortest distance between the pollution source position of the harmful substance in the harmful substance information and each of the second water system paths is calculated, and the water system corresponding to the second water system path whose shortest distance is less than the first set distance is taken as the target water system, thereby obtaining the water system that may be contaminated by the harmful substances, and taking the water system path section in the water system path of the target water system whose distance from the pollution source position is less than the second set distance as the polluted section, and obtaining the water flow velocity and water flow cross-sectional area of ​​the polluted section corresponding to the target water system through the sub-environment information. The product of the water flow velocity and the water flow cross-sectional area reflects the polluted section. The water flow rate per unit time is obtained through the sub-geological information corresponding to the above-mentioned sub-region. The soil permeability between the above-mentioned pollution source and the above-mentioned pollution section is obtained. The above-mentioned soil permeability, the above-mentioned harmful substance concentration, and the distance between the location of the above-mentioned pollution source and the above-mentioned pollution section jointly determine the penetration rate of the harmful substance. Therefore, by inputting the water flow velocity and water flow cross-sectional area of ​​the above-mentioned pollution section and other sections, the above-mentioned harmful substance concentration, the distance between the location of the above-mentioned pollution source and the above-mentioned pollution section, and the soil permeability between the above-mentioned pollution source and the above-mentioned pollution section into the pollution prediction sub-model corresponding to the above-mentioned sub-region in the above-mentioned pollution prediction model, the pollution range and pollution degree caused by the above-mentioned pollution source to the above-mentioned target water system that changes with time are obtained. The above-mentioned pollution degree is the concentration of harmful substances in the above-mentioned target water system, wherein the above-mentioned pollution prediction model is a distributed model, and multiple pollution prediction sub-models in the above-mentioned pollution prediction model can simultaneously predict the pollution situation in the corresponding sub-region. Through the above-mentioned technical solution, the pollution range and pollution degree of each pollution source in each sub-region to the corresponding target water system that changes with time can be accurately obtained.

[0029] Furthermore, the pollution prediction model includes N pollution prediction sub-models, where N is the number of the sub-areas, and the value range of N is a positive integer greater than or equal to 2.

[0030] Specifically, the above-mentioned pollution prediction model is a distributed model, and the above-mentioned pollution prediction model includes N above-mentioned pollution prediction sub-models. The above-mentioned pollution prediction sub-models are trained respectively through the historical pollution data of the corresponding sub-areas. The above-mentioned historical pollution data include historical harmful substances, water flow velocity and water flow cross-sectional area of ​​the polluted section and other sections of each water system in the above-mentioned sub-areas, the concentrations corresponding to multiple above-mentioned harmful substances, the distance between the location of the historical pollution source and the polluted section of the corresponding water system, the soil permeability between the historical pollution source and the polluted section of the corresponding water system, and the historical pollution range and historical pollution degree of the above-mentioned water system changing with time. Through the above-mentioned technical solution, when multiple sub-areas are constructed simultaneously in the above-mentioned target development area, the corresponding pollution prediction sub-models in the above-mentioned pollution prediction model can be used to simultaneously predict the pollution situation of the corresponding sub-areas, so as to facilitate timely taking of corresponding measures during construction to prevent the deterioration of pollution.

[0031] Further, obtaining the water environment assessment result of the target development area includes: Obtain all pollution information corresponding to all pollution sources in the sub-area, and determine whether the pollution range corresponding to each pollution source in the sub-area and the pollution range corresponding to each pollution source in the adjacent sub-area intersect; if they do not intersect, obtain the second risk score based on the all pollution information of the sub-area and the corresponding second scoring standard; if they intersect, when the intersection position is located in the sub-area, add the pollution information at the corresponding intersection position of the adjacent sub-area to the all pollution information of the sub-area to obtain the total pollution information, and obtain the second risk score based on the total pollution information and the second scoring standard; use the first risk score and the second risk score corresponding to the sub-area as the sub-risk assessment result corresponding to the sub-area, and use the risk level corresponding to the average value of all the sub-risk assessment results corresponding to all the sub-areas as the water environment assessment result of the target development area.

[0032] Specifically, since there are multiple sub-areas with different construction processes being carried out simultaneously in the target development area, and since the water systems in adjacent sub-areas intersect, it is possible that the pollution ranges in multiple adjacent sub-areas may overlap over time. This situation needs to be considered when analyzing the total pollution information of the sub-areas. Since there is more than one pollution source in each sub-area, all pollution information corresponding to all pollution sources in the sub-areas is obtained, and the pollution range in the pollution information corresponding to each pollution source in the sub-area is compared with the pollution range in the pollution information corresponding to each pollution source in the adjacent sub-area, wherein the pollution range changes over time. When the two do not intersect, the second risk score of the sub-area is obtained based on the above-mentioned all pollution information in the sub-area and the above-mentioned second scoring standard, wherein the above-mentioned second scoring standard is a scoring standard for evaluating the pollution range and pollution degree of the sub-area. When they intersect and the intersection position is located in the sub-area, that is, in the adjacent sub-area, Sewage flows into the above-mentioned sub-area, and the pollution information at the intersection position, i.e., the intersection range, pollution concentration and intersection time, is added to the total pollution information of the above-mentioned sub-area to obtain the total pollution information, and the second risk score corresponding to the above-mentioned sub-area is obtained according to the above-mentioned total pollution information and the above-mentioned second scoring standard, and the above-mentioned first risk score and the above-mentioned second risk score corresponding to the above-mentioned sub-area are used as the sub-risk assessment result of the above-mentioned sub-area, and the risk level of the average value of the sub-risk assessment results in all the above-mentioned sub-areas is used as the water environment assessment result of the above-mentioned target development area, wherein the above-mentioned sub-risk assessment result average value is the first risk score average value and the second risk score average value, and the above-mentioned risk level is obtained according to the risk level classification standard, and the above-mentioned risk level classification standard can be defined according to user needs. Through the above-mentioned technical solution, the risk level of the above-mentioned target development area that changes with time and the first risk score and the above-mentioned second risk score that change with time of each sub-area can be accurately obtained, so that users can take timely measures to prevent pollution from worsening during construction.

[0033] Furthermore, after obtaining each pollution information of the sub-area, the pollution information is also displayed in the three-dimensional twin model and presented through animation.

[0034] Specifically, through the above technical solution, the pollution range and pollution degree in the above sub-area that change with time can be intuitively displayed.

If there is a conflict, a correction path is obtained to ensure normal construction while minimizing the change in the water environment, and compares the water system characteristics corresponding to the above-mentioned correction path with the water system characteristics corresponding to the above-mentioned conflicting path. According to the above-mentioned comparison result and the first evaluation standard, the above-mentioned first risk score is obtained.
