Description

Technical Field

[0001] This invention relates to the technical field of construction progress assessment and management, specifically to an assessment system and method for the construction progress of long tunnels with complex geological conditions. Background Technology

[0002] Because a tunnel is a long, tubular structure, tunnel construction is a multi-stage, multi-trade underground operation characterized by narrow working faces, limited capacity for workers, numerous work cycles, large volumes of muck and material transportation, strong inter-process interference, high difficulty in construction organization, and slow progress in excavation and support. Typically, only two working faces continuously advance in a loop, and sometimes even these two faces are not fully utilized. Adding more working faces is also difficult. Therefore, tunnel engineering often becomes a key project for controlling the construction period, with a challenging timeline.

[0003] The geological conditions of some extra-long tunnels, extremely high-risk tunnels, and key control tunnels in southern Yunnan are complex, with prominent adverse geological problems such as active faults, large deformation of soft rock, karst, water-rich structures, bedding planes, and high ground temperatures, resulting in high construction risks and extreme difficulty. To ensure the steady, orderly, and accelerated construction of key control tunnel projects, and in accordance with the operational goal of ensuring the high-quality opening of a certain railway, the construction of key tunnels is being steadily and comprehensively advanced based on the specific circumstances of the project, ensuring the achievement of key schedule targets.

[0004] Currently, most methods for assessing tunnel construction progress indicators focus on the overall completion date and key milestones. A few methods use monthly excavation and support progress targets based on surrounding rock grade, drawing upon tunnel construction experience. However, most existing methods rely on single-face excavation progress assessments, failing to provide real-time adjustments to monthly progress indicators, lack a clear view of critical path milestones, and are ineffective in setting assessment points for key control points. Therefore, a better assessment system and method are needed to evaluate the completion of key control tunnel excavation and support construction progress indicators within a project section, ensuring the effectiveness of rewards and penalties based on assessment results. Summary of the Invention

[0005] To address the technical problems existing in current performance evaluation and management systems, this invention provides a performance evaluation system and method for the construction progress of long tunnels in complex geological conditions. This system and method provide a management system and method for evaluating the completion of construction progress indicators for tunnels in complex geological conditions and tunnels used in control projects.

[0006] To achieve the above objectives, this invention provides a method for assessing the construction progress of long tunnels in complex geological conditions. The method is implemented through a system for assessing the construction progress of long tunnels in complex geological conditions and includes the following steps: S1. Receive the basic information of the assessment subject at the beginning of the current period through the data acquisition module; S2. Receive the required information on the current period's assessment completion status for each path of the assessment target through the indicator element analysis and calculation module; S3. Process the path weight information and path completion percentage information of the assessed object, and output the current assessment record information of the assessed object; S4. Store the assessment results of the assessed individuals in the storage module; S5. When the storage module receives a query instruction, it reads the assessment results of the assessment object from the storage module according to the query instruction and outputs the assessment results to the display module.

[0007] In step S1, the construction unit client of the data acquisition module receives the basic information of each path of the assessment object at the beginning of the current period, including: the planned completion date, the remaining construction period, the path weight, the remaining amount of work at the beginning of the period, and other explanatory information.

[0008] In step S2, the construction unit client receives the required information on the current period's assessment completion status of each path through the indicator element analysis and calculation module, including: the current period's planned progress, the current period's actual completion progress, and the path completion percentage.

[0009] Step S3 specifically includes: adopting an assessment method based on the comprehensive percentage completion of the excavation and support plan for a single tunnel within a section, whereby the percentage is named the Joss percentage or Joss score, denoted by Q; the Joss percentage Q is calculated as a weighted average of the percentage completion of excavation and support for the remaining paths of each tunnel section in the current month; seeking an expression for the combination of elements of the construction progress indicator system that affect the assessment results for each path, thus obtaining the calculation formula for the tunnel construction progress indicator assessment: (1) In the formula: λ is the schedule indicator correction factor, with a value range of 0.95 ≤ λ ≤ 1.05; Ki represents the percentage of planned completion for each remaining path; AI is the weight coefficient or percentage for each remaining path; n is the number of remaining paths; Percentage of remaining path completed (Ki): (2) In the formula: pi represents the actual number of remaining paths completed in the current month, which is the sum of the actual completion amounts of the two working faces; if the two working faces belong to different sections, it is the completion amount of a single working face within the assessment section. Pi represents the planned quantity of the remaining path to be completed in the current month, determined by the remaining path length and the remaining construction period, and converted into monthly progress; the remaining quantity of work is the remaining path length up to the beginning of the assessment period; the remaining construction period is the time from the beginning of the assessment period to the date of completion, converted into months. The weighting coefficient Ai for the remaining paragraphs: (3) In the formula: li represents the remaining path length up to the beginning of the assessment period; L represents the total remaining path length up to the beginning of the assessment period.

[0010] The remaining paths for the section include: the routes taken to achieve breakthrough for the remaining sections of the tunnel identified as the assessment targets.

[0011] The elements of the construction progress indicator system that affect the assessment results include: planned completion date Tp, remaining construction period Ts, path weight Ai, initial remaining work volume li, current planned progress Pi, current actual completed progress pi, path completion percentage Ki, and other explanatory information, totaling 8 influencing factors.

[0012] Other explanatory circumstances include: if the remaining path involves one auxiliary tunnel entering the main tunnel and the roof is lifted, the remaining construction period will be reduced by 0.5 months; if the auxiliary tunnel enters the main tunnel and the roof is lifted twice, the remaining construction period will be reduced by 1.0 month; the completion date of each remaining section will be specified by the construction unit's assessment department according to the construction organization design.

[0013] Whether to use the progress index correction coefficient in the above formula (1), and how to determine its value, shall be determined by the assessment department of the construction unit and the construction unit being assessed.

[0014] The complex geological tunnels include: extra-long tunnels, extremely high-risk tunnels, and control tunnels with prominent geological problems such as complex geology, active faults, large deformation of soft rock, karst, water-rich structures, bedding planes, and high ground temperature, which pose high engineering construction risks and are difficult to construct.

[0015] An assessment system for evaluating the construction progress of long tunnels in complex geological conditions includes a server, a client application for assessing construction units, and a terminal application for assessing construction companies. The server comprises Server 1 and Server 2. Server 1 includes a data acquisition module and an indicator element analysis and calculation module, while Server 2 includes an assessment module and a reward / penalty evaluation module. The assessment system also includes a base station module, a data analysis module, a storage module, and a display module.

[0016] The data acquisition module is connected to the construction unit's client, the indicator element analysis and calculation module, and the assessment module via a base station module. The indicator element analysis and calculation module is connected to the construction unit's client and the assessment module via a base station module. The assessment module is connected to the construction unit's terminal, the base station module, the reward and penalty evaluation module, and the storage module. The storage module is connected to the display module.

[0017] The base station module is connected to the data acquisition module, the indicator element analysis and calculation module, the data analysis module, and the assessment module, respectively.

[0018] The data acquisition module is used to receive basic information of the initial indicator elements of the assessment object from the client of the construction unit, and to feed the collected information back to the indicator element analysis and calculation module. The indicator element analysis and calculation module is used to receive the requirement information from the construction unit's client regarding the current completion status of each path of the assessment object, and to summarize the information collected by all clients during the current assessment period. The summarized information is then used for data identification and analysis according to the assessment method. The weight coefficient Ai of the remaining section and the completion percentage Ki of the remaining path of the assessment object are obtained through the calculation formula of the tunnel construction progress indicator assessment. The current assessment result record information of the assessment object is output and the assessment result is fed back to the assessment module. The assessment module is used to receive basic information of the initial indicators of the assessed object from the data acquisition module through the base station module; to receive the assessment results calculated by the indicator element analysis and calculation module through the base station module, and to feed the assessment results back to the reward and punishment evaluation module; the assessment cycle of the assessment module is from the 21st of each month to the 20th of the following month, and on the 20th of the following month, an indicator element information table of the assessment completion status is sent to the construction unit client.

[0019] The reward and punishment assessment module is connected to the construction unit's terminal. Based on the assessment results of the assessment module, the module assesses whether the construction unit's assessment targets are rewarded or punished, feeds back the assessment results to the construction unit's terminal, and stores them through the storage module.

[0020] The storage module is used to store the current assessment results and the current reward and punishment evaluation results, and reads the target assessment results according to the query command, and outputs the assessment results to the display module.

[0021] The display module is used to display the target assessment results.

[0022] This invention provides a system and method for assessing the construction progress of long tunnels in complex geological conditions. It successfully addresses a series of problems, including limited excavation and construction at the tunnel face, the fact that tunnels are often key control projects within a construction section, tight deadlines, incomplete progress assessment indicators, unclear percentage completion rates for different remaining paths, vague weighting coefficients for remaining segments of those paths, and ambiguous relationships between remaining critical path work and remaining time. These issues lead to ineffective incentive assessment mechanisms and unclear assessment results. Through innovative research, the invention proposes using the comprehensive percentage completion of excavation and support plans for individual tunnels within a construction section. This effectively solves the above problems and more concretely and intuitively reflects the percentage completion and remaining work of the critical path during the assessment period, resulting in more effective assessment results.
