[0002] Tunnel construction progress indicators refer to a system of metrics used to measure the progress of tunnel construction. These indicators reflect the advancement of tunnel construction, helping project managers to identify and resolve problems promptly, ensuring both construction quality and project schedule adherence.

[0003] In the current process of monitoring tunnel construction progress, the current construction progress is often reported directly or inquired about through superiors. However, it is unclear whether the current construction progress is truly reasonable. This leads to a lack of feasible progress per unit time period in the monitoring of tunnel construction progress, resulting in a lack of reasonable evaluation standards, inaccurate evaluation of construction progress monitoring, and an inability to meet the needs of progress control. Summary of the Invention

[0011] In one embodiment of the present invention, the risk monitoring unit includes: a data extraction subunit, used to extract data from the monitored construction data according to the data demand type of the current progress block corresponding to the current construction cycle, to obtain multiple construction feature data corresponding to the data demand type; a feature comparison subunit, used to compare each construction feature data with a corresponding feature threshold; when a construction feature data is greater than the corresponding feature threshold, the difference between the construction feature data and the feature threshold is calculated to obtain a feature difference; based on the feature difference and the construction risk coefficient corresponding to the feature difference, the construction risk index of the current progress block is obtained; and a risk monitoring subunit, used to monitor the construction risk index of the current progress block for risk thresholds; when the construction risk index is greater than the risk threshold, a monitoring result indicating that there is construction risk in the current progress block is obtained; when the construction risk index is less than the risk threshold, a monitoring result indicating that there is no construction risk in the current progress block is obtained.

[0012] In one embodiment of the present invention, the formula for calculating the construction risk index is as follows: ,in, Indicators representing construction risk. Represents construction characteristic data, This represents the feature threshold corresponding to each construction feature data point. This represents the construction risk coefficient corresponding to each feature difference. This indicates the number of feature differences.

[0013] In one embodiment of the present invention, the second control output unit optimizes the length of the base block of the next progress block corresponding to the next construction cycle based on the historical construction risk index corresponding to the historical construction cycle and the current construction risk index corresponding to the current progress block, to obtain an optimized block length, and then performs tunnel construction of the next progress block corresponding to the next construction cycle using the optimized block length. The process includes: a risk change prediction subunit, used to calculate the risk difference between the current construction risk index and the historical construction risk index when multiple current progress blocks in the same geological segment have current construction risk indices greater than the historical construction risk index corresponding to the historical construction cycle; and obtaining the linear change rate of the risk difference based on the risk difference; a coefficient query subunit, used to look up the block length adjustment coefficient corresponding to the remaining progress block in the corresponding geological segment based on the linear change rate; and a construction optimization subunit, used to calculate the optimized block length corresponding to the remaining progress block based on the block length adjustment coefficient and the base block length corresponding to the remaining progress block, and perform tunnel construction of the next progress block corresponding to the next construction cycle based on the optimized block length of the next progress block corresponding to the next construction cycle.

[0014] To achieve the above and other related objectives, the present invention also provides a method for monitoring tunnel construction progress, comprising: acquiring the tunnel design route through a route acquisition unit; obtaining a tunnel geological model through a model construction unit based on the tunnel design route and corresponding geological exploration data through a model construction unit; dividing the tunnel geological model into blocks of varying lengths through a block division unit to obtain multiple consecutive progress blocks, each progress block corresponding to a construction cycle; and, after the completion of the tunnel construction procedures in the current construction cycle, conducting construction risk monitoring on the current progress block based on the construction characteristic data of the current progress block corresponding to the current construction cycle through a risk monitoring unit, and obtaining monitoring results; and so on. When the monitoring result of the first control output unit indicates that there is no construction risk in the current progress block, the construction progress corresponding to the current progress block is completed, and tunnel construction continues using the base block length of the next progress block corresponding to the next construction cycle. When the monitoring result of the second control output unit indicates that there is a construction risk in the current progress block, the base block length of the next progress block corresponding to the next construction cycle is optimized based on the historical construction risk indicators corresponding to the historical construction cycles and the current construction risk indicators corresponding to the current progress block, so as to obtain the optimized block length, and the tunnel construction of the next progress block corresponding to the next construction cycle is carried out using the optimized block length.

[0015] The beneficial effects of this invention are as follows: The tunnel construction progress monitoring system and method proposed in this invention obtain the tunnel design route corresponding to the spatial geometry of the tunnel to be constructed. Further, by combining this with geological exploration data obtained from actual exploration and surveying based on the tunnel design route, a tunnel geological model can be constructed. This model not only represents the spatial geometry but also the geological attributes related to the actual exploration. Then, based on the geological characteristics of the tunnel geological model, the model is precisely divided into progress blocks to ensure that each progress interval meets a construction cycle. This allows for the quantification of tunnel construction progress in units of construction cycles, achieving not only the measurement of the construction cycle but also quantitative monitoring of construction progress, thus improving construction efficiency. Furthermore, after initially determining the progress blocks, to ensure that the progress blocks remain consistent with actual construction and to reduce the risk of reduced tunnel construction quality due to excessively rapid construction, construction risk monitoring can be performed on the current progress block after each construction cycle is completed, using the construction characteristic data of the current progress block corresponding to the current construction cycle. When no construction risks exist, tunnel construction continues using the basic block length of the next progress block corresponding to the next construction cycle. However, if construction risks exist, historical construction risk indicators for previous construction cycles and current construction risk indicators for the current progress block can be comprehensively analyzed to optimize the basic block length of the next progress block for the next construction cycle. This optimized block length can then be used for tunnel construction in the next progress block of the next construction cycle. Furthermore, while optimizing the basic block length of the next progress block, the basic block lengths of the remaining progress blocks for other remaining construction cycles can also be optimized to achieve quantitative block optimization and monitoring of the entire construction progress.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0022] Please see Figure 1This invention provides a tunnel construction progress monitoring system, comprising: a route acquisition unit 111 for acquiring the tunnel design route; a model construction unit 112 for obtaining a tunnel geological model based on the tunnel design route and corresponding geological exploration data; a block division unit 113 for dividing the tunnel geological model into blocks of varying lengths to obtain multiple consecutive progress blocks, each progress block corresponding to a construction cycle; a risk monitoring unit 114 for monitoring the construction risks of the current progress block after the completion of the tunnel construction procedures in the current construction cycle, based on the construction characteristic data of the current progress block corresponding to the current construction cycle, and obtaining monitoring results; and a first control unit. The output unit 115 is used to complete the construction progress corresponding to the current progress block when the monitoring result indicates that there is no construction risk in the current progress block, and continue tunnel construction by using the base block length of the next progress block corresponding to the next construction cycle; and the second control output unit 116 is used to optimize the base block length of the next progress block corresponding to the next construction cycle based on the historical construction risk index corresponding to the historical construction cycle and the current construction risk index corresponding to the current progress block when the monitoring result indicates that there is a construction risk in the current progress block, so as to obtain the optimized block length, and carry out tunnel construction of the next progress block corresponding to the next construction cycle by using the optimized block length.

[0023] As can be seen from the above, during tunnel construction progress management, the route acquisition unit 111 can obtain the tunnel design route corresponding to the spatial geometry of the tunnel to be constructed. Furthermore, the model construction unit 112, combined with geological exploration data obtained from actual exploration and surveying based on the tunnel design route, can further construct a tunnel geological model. This model can not only represent the spatial geometry but also the geological attributes related to the actual exploration. Then, the block division unit 113, based on the geological characteristics of the tunnel geological model, can accurately divide the tunnel geological model into progress blocks, ensuring that each progress interval meets a construction cycle. This allows for the quantification of tunnel construction progress in units of construction cycles, achieving not only effective measurement of the tunnel construction cycle but also quantitative monitoring of construction progress, thereby improving construction efficiency. Furthermore, after initially determining the progress blocks, to ensure that the progress blocks remain consistent with actual construction and to reduce the risk of reduced tunnel construction quality due to excessively rapid construction, the risk monitoring unit 114 can monitor the construction risks of the current progress block after each construction cycle is completed, using the construction characteristic data of the current progress block corresponding to the current construction cycle. If no construction risk exists, the first control output unit 115 continues tunnel construction using the basic block length of the next progress block corresponding to the next construction cycle. If a construction risk exists, the second control output unit 116 can comprehensively analyze the historical construction risk indicators corresponding to historical construction cycles and the current construction risk indicators corresponding to the current progress block to optimize the basic block length of the next progress block corresponding to the next construction cycle. This optimized block length can then be used for tunnel construction in the next progress block corresponding to the next construction cycle. Of course, while optimizing the basic block length of the next progress block, the basic block length of the remaining progress blocks corresponding to other remaining construction cycles can also be optimized to achieve quantitative block optimization and monitoring of the entire construction progress.

[0024] In the tunnel construction progress monitoring system of the present invention, the model building unit 112 includes: a model building subunit, used to obtain a tunnel geometric model based on the tunnel design route and the cross-sectional design dimensions corresponding to the tunnel design route; a geological attribute query subunit, used to obtain the geological attribute distribution data of the geological area corresponding to the tunnel geometric model based on geological exploration data; and a model generation subunit, used to add the geological attribute distribution data to the tunnel geometric model to obtain a tunnel geological model.

[0025] In constructing the tunnel geological model, the model building module 112 can first use the tunnel design route (including its linearity and corresponding cross-sectional dimensions) to build the corresponding tunnel geometric model through the geometric model building sub-unit. Then, the geological attribute query sub-unit extracts the geological exploration data obtained from the exploration, corresponding to the tunnel geometric model, thereby obtaining the geological attribute distribution data of the geological area corresponding to the tunnel geometric model. Finally, the model generation sub-unit adds the geological attribute distribution data to the tunnel geometric model, thus constructing a tunnel geological model that possesses both geometric structural parameters and geological attribute data. This allows for accurate segmentation of the tunnel geological model based on its geological attributes.

[0026] In the tunnel construction progress monitoring system of the present invention, the block division unit 113 includes: a segment division subunit, used to obtain multiple continuous geological segments based on the geological attribute distribution data corresponding to the tunnel geological model; an attribute comparison subunit, used to compare the similarity of historical geological attribute distribution data based on the geological attribute distribution data of each geological segment, so as to obtain the historical geological attribute distribution data that reaches a specified similarity and is closest to the geological attribute distribution data; and a block generation subunit, used to query the block length division specification data corresponding to the historical geological attribute distribution data that reaches a specified similarity and is closest to the geological attribute distribution data, divide the geological segments, and obtain multiple continuous progress blocks.

[0027] When dividing the tunnel geological model into progress blocks, the block division unit 113 can first use the segment division subunit based on the geological attribute distribution data corresponding to the tunnel geological model, such as the rock strata distribution data along the cross-section of the model through which the tunnel passes. Based on the similarity of this distribution data, the tunnel geological model can be divided into multiple continuous geological segments; for example, when the rock strata distribution data are similar, they can be considered as the same geological segment. The attribute comparison subunit compares the similarity of the geological attribute distribution data of each geological segment with historical geological attribute distribution data to find the historical geological attribute distribution data that reaches the specified similarity. Then, based on the block length division specification data corresponding to this historical geological attribute distribution data, the geological segments are divided to obtain multiple continuous progress blocks. The system pre-stores a correspondence table between historical geological attribute distribution data and block length division specification data, allowing direct retrieval of the corresponding block length division specification through the historical geological attribute distribution data, thereby realizing the division of geological segments.

[0028] Preferably, the progress block includes spliced ​​progress blocks and non-spliced ​​progress blocks, and the geological segment includes the first segment, the middle segment and the last segment.

[0029] The block generation subunit may further include: a duration extraction module, used to extract the remaining duration of the previous construction cycle after non-splicing progress block splicing of the previous tail segment of the previous geological segment; a specification query module, used to query the historical geological attribute distribution data that reaches a specified similarity and is closest to the target geological attribute distribution data of the target geological segment in the historical geological attribute distribution database, and use the block length division specification data of the historical geological attribute distribution data as the target block length division specification data corresponding to the target geological segment; and a previous block division splicing module, used to perform length division splicing on the target first segment of the target geological segment based on the target block length division specification data and the previous remaining duration. The system employs several methods: a progress segmentation module to connect the first segment of the target geological segment with the last segment of the previous geological segment corresponding to the previous remaining time, resulting in the previous splicing progress block; a non-splicing segmentation module to sequentially divide the target middle segment of the target geological segment according to the segment length specification data, resulting in the target non-splicing progress block; a target segment tail time calculation module to divide the target tail segment of the target geological segment according to the segment length specification data, resulting in the construction cycle occupancy time corresponding to the target tail segment; and a target segment splicing module to divide the next segment of the next geological segment according to the construction cycle occupancy time corresponding to the target tail segment, resulting in the target splicing progress block.

[0030] When dividing geological segments, the block generation subunit can use a duration extraction module to extract the remaining duration of the previous construction cycle after the non-splicing progress blocks of the previous geological segment are spliced ​​together. In other words, after the corresponding non-splicing progress blocks of the previous geological segment are completed in each construction cycle, the last construction cycle is incomplete, resulting in a remaining duration corresponding to the previous remaining duration of the construction cycle. Then, the specification query module searches a pre-configured historical geological attribute distribution database for historical geological attribute distribution data that is closest in similarity to the target geological segment's target geological attribute distribution data, which contains multiple historical geological attribute distribution data. After obtaining the historical geological attribute distribution data, the corresponding block length division specification data is also obtained and used as the target block length division specification data for the target geological segment. The previous block segmentation and splicing module further utilizes the target block length segmentation specification data, combined with the previous remaining time, to sequentially segment the target first segment of the target geological fragment according to its length attribute. This allows for the splicing of the target first segment with the previous last segment of the previous geological fragment corresponding to the previous remaining time, thus enabling the completion of the last construction cycle of the previous geological fragment. Construction content is then supplemented using the target first segment of the target geological fragment, resulting in the previous splicing progress block based on the last construction cycle of the previous geological fragment. Simultaneously, the target non-sponge-jointing segmentation module, after segmenting the target first segment of the target geological fragment, can further segment the middle section following the target geological fragment, using the corresponding block length segmentation specification data, thereby obtaining multiple target non-sponge-jointing progress blocks corresponding to the target middle section. Similarly, at the end of the target geological segment, there will also be a tail section that is less than one construction cycle. Therefore, the target block tail section time calculation module can use the corresponding block length division specification data to divide the target geological segment into its tail section, thereby obtaining the construction cycle time required for the tail section, which is the time required to construct the tail section that is less than one construction cycle. Finally, the target block division and splicing module uses the construction cycle time corresponding to the target tail section to determine the length of the next segment of the next geological segment, that is, to obtain the target splicing progress block. This enables precise positioning of the executable construction progress for each construction cycle when monitoring tunnel construction progress. That is, by using non-splicing progress blocks and splicing progress blocks, the corresponding tasks in each construction cycle are completed sequentially, achieving quantitative and dynamic control of the construction progress corresponding to each construction cycle.

[0031] In addition, the previous splicing progress block, the target non-splicing progress block, and the target splicing progress block can be further divided sequentially by dividing the previous splicing module, the target non-splicing progress block, and the target splicing progress block, so as to ensure that each progress block can correspond to a construction cycle.

[0032] Specifically, the previous block segmentation and splicing module can also be used to calculate the difference between the construction cycle and the third previous occupancy time corresponding to the previous tail segment of the previous geological segment, to obtain the previous remaining time, which is used as the first target occupancy time of the target first segment of the target geological segment; extract the construction speed parameter from the target block length segmentation specification data to obtain the first target construction speed of the unit block length corresponding to the target geological segment; calculate the target first segment length of the target geological segment based on the first target construction speed and the first target occupancy time; and superimpose the target first segment length and the previous tail segment length of the previous geological segment to generate the basic splicing length of the previous splicing progress block, so as to obtain the previous splicing progress block.

[0033] The calculation formula for the previous splicing progress block can be expressed as: , in, This indicates the third preceding time segment of the preceding geological segment. Indicates the construction period. Indicates the remaining time of the previous period. This represents the first target construction speed per unit block length corresponding to the target geological segment. This indicates the length of the first segment of the target geological fragment. This indicates the length of the preceding segment of the previous geological fragment. This indicates the base splicing length of the previous splicing progress block. It represents the third previous occupied time for the previous tail segment of the previous geological fragment. This could be based on the completion of the remaining portion after all the non-splicing progress corresponding to the previous middle section of the previous geological segment has been determined. The first target construction speed for the unit block length corresponding to the target geological segment. , No. The second objective is the construction speed corresponding to the unit block length of the non-joined progress block. The third target construction speed corresponding to the unit block length of the target tail segment of the target geological fragment. All of these can be extracted from the target block length division specification data. In other words, the target block length division specification data pre-determines the construction speeds corresponding to each historical geological attribute distribution data through manual annotation. These construction speeds can be pre-determined manually based on actual construction results, and then adaptively interpolated based on the length of each geological segment to obtain the construction speed corresponding to the corresponding length of the geological segment. Similarly, the first construction speed per unit block length corresponding to the next tail segment of the next geological segment is also extracted from the next block length division specification data corresponding to the next geological segment. Construction cycle It can be based on the pre-set duration of a single construction session, such as in days or months, or other unit time lengths.

[0034] Next, the target non-stitched progress block can also be used to extract construction speed parameters from the target block length division specification data to obtain the second target construction speed for each target non-stitched progress block per unit block length; the construction cycle is used as the second target occupancy time of the target middle section of the target geological segment; the product of each second target construction speed and the second target occupancy time is calculated to generate the basic stitching length of each target non-stitched progress block, so as to obtain the target non-stitched progress block.

[0035] The calculation formula for the target non-joined progress block can be expressed as: ; in, Indicates the first The base splicing length for each target non-splicing progress block. Indicates the first The second target construction speed corresponds to the unit block length of the non-joined progress block of the target.

[0036] Finally, the target splicing progress block can also be used to calculate the difference between the total length of the geological segment and the length of the target first segment and the basic splicing length of each target non-splicing progress block, to obtain the target tail segment length of the target geological segment; extract the construction speed parameter from the target block length division specification data to obtain the third target construction speed for the unit block length corresponding to each target splicing progress block; calculate the third target occupancy time for the target tail segment length of the target geological segment based on the target tail segment length and the third target construction speed; calculate the difference between the construction cycle and the third target occupancy time to obtain the target remaining time, which is used as the first next occupancy time for the next first segment of the next geological segment; extract the construction speed parameter from the next block length division specification data to obtain the first next construction speed for the unit block length corresponding to each next splicing progress block; multiply the first next occupancy time and the first next construction speed to obtain the next tail segment length of the next geological segment; sum the next tail segment length and the target tail segment length to generate the basic splicing length of the target splicing progress block, thus obtaining the target splicing progress block.

[0037] The formula for calculating the target stitching progress block can be expressed as: , in, This represents the total length of each geological segment. Indicates the length of the target tail segment of the target geological fragment. The time occupied by the third target, representing the length of the target tail segment of the target geological fragment. The third target construction speed represents the unit block length corresponding to the target tail segment of the target geological fragment. Indicates the remaining time of the target. This indicates the first next construction speed corresponding to the next tail segment of the next geological segment, per unit block length. Indicates the length of the next tail segment of the next geological segment. Indicates the basic splicing length of the target splicing progress block.

[0038] In the tunnel construction progress monitoring system of the present invention, the risk monitoring unit 114 includes: a data extraction subunit, used to extract data from the monitored construction data according to the data demand type of the current progress block corresponding to the current construction cycle, and obtain multiple construction feature data corresponding to the data demand type; a feature comparison subunit, used to compare each construction feature data with the corresponding feature threshold; when there is a construction feature data greater than the corresponding feature threshold, the difference between the construction feature data and the feature threshold is calculated to obtain the feature difference; based on the feature difference and the construction risk coefficient corresponding to the feature difference, the construction risk index of the current progress block is obtained; and a risk monitoring subunit, used to monitor the risk threshold of the construction risk index of the current progress block; when the construction risk index is greater than the risk threshold, the monitoring result that there is construction risk in the current progress block is obtained; when the construction risk index is less than the risk threshold, the monitoring result that there is no construction risk in the current progress block is obtained.

[0039] During the division of each progress block, corresponding data requirement types are obtained based on the relevant historical geological attribute distribution data, and these data requirement types are pre-stored in the system. Therefore, during construction risk monitoring, the risk monitoring unit 114 can first use the data extraction subunit to extract the required construction feature data based on the data requirement type of the current progress block corresponding to the current construction cycle. It is worth noting that each historical geological attribute distribution data corresponds to a different data requirement type. Therefore, by using the data requirement type to retrieve the corresponding construction feature data, the accuracy of the construction risk index calculation can be effectively guaranteed. Furthermore, during the calculation of the construction risk index, the feature comparison subunit can compare each construction feature data with the corresponding feature threshold. When a construction feature data is greater than the corresponding feature threshold, the difference between the construction feature data and the feature threshold can be further calculated to obtain the feature difference. Then, by using each feature difference and the corresponding construction risk coefficient, a comprehensive calculation can be performed to obtain the construction risk index of the current progress block in the current construction cycle. Furthermore, the risk monitoring subunit can monitor the construction risk indicators of the current progress block by setting risk thresholds. When the construction risk indicator is greater than the risk threshold, it indicates that there is a construction risk in the current progress block. When the construction risk indicator is less than the risk threshold, it indicates that there is no construction risk in the current progress block. The corresponding presence or absence of construction risk can be output as monitoring results to the first control output unit 115 or the second control output unit 116 to accurately control the execution of the corresponding construction strategy.

[0040] Preferably, the formula for calculating the construction risk index can be expressed as: , in, Indicators representing construction risk. Represents construction characteristic data, This represents the feature threshold corresponding to each construction feature data point. This represents the construction risk coefficient corresponding to each feature difference. This represents the number of feature differences. The feature threshold corresponding to each construction feature data point. The construction risk coefficient corresponding to each feature difference can be preset manually. It can be obtained manually based on the conversion relationship between each feature difference and the construction risk index.

[0041] Construction features can include millimeter-wave radar point cloud data, surrounding rock stress, concrete pressure stabilization, vibration energy, microseismic monitoring array data, thermal infrared imaging data, construction machinery operation status bus data, etc. The construction feature data can be surrounding rock stress, concrete pressure stabilization, vibration energy, and microseismic monitoring array data, etc. Specifically, the data requirement type of construction feature data can be manually calibrated in advance according to the specific needs of the indicator risk.

[0042] In the tunnel construction progress monitoring system of the present invention, the second control output unit 116 optimizes the block length of the base block of the next progress block corresponding to the next construction cycle based on the historical construction risk index corresponding to the historical construction cycle and the current construction risk index corresponding to the current progress block, and obtains the optimized block length so as to carry out tunnel construction of the next progress block corresponding to the next construction cycle through the optimized block length. The system includes: a risk change prediction subunit, used to calculate the risk difference between the current construction risk index and the historical construction risk index when there are multiple current construction risk indices corresponding to the current progress blocks that are greater than the historical construction risk indices corresponding to the historical construction cycles in the same geological segment; and obtains the linear change rate of the risk difference based on the risk difference; a coefficient query subunit, used to look up the block length adjustment coefficient corresponding to the remaining progress block in the corresponding geological segment based on the linear change rate; and a construction optimization subunit, used to calculate the optimized block length corresponding to the remaining progress block based on the block length adjustment coefficient and the base block length corresponding to the remaining progress block, and carry out tunnel construction of the next progress block corresponding to the next construction cycle based on the optimized block length of the next progress block corresponding to the next construction cycle.

[0043] During the block length optimization process, the second control output unit 116 can first use the risk change prediction subunit to calculate the risk difference between the current construction risk index and the historical construction risk index for the same geological segment when multiple current progress blocks have a higher current construction risk index than the historical construction cycle. The curve between the construction cycle and the risk difference is linear, for example, the linear rate of change of the risk difference can be obtained using the least squares method. Then, the coefficient query subunit uses this linear rate of change to find the block length adjustment coefficient for the remaining progress blocks in the corresponding geological segment, including the next block length adjustment coefficient for the next construction cycle. The correspondence between each linear rate of change and the block length adjustment coefficient can be preset manually. Then, the construction optimization subunit uses the block length adjustment coefficient to optimize the length of the basic block corresponding to the remaining progress block. That is, by multiplying the length of the basic block corresponding to the remaining progress block with the block length adjustment coefficient, the optimized block length corresponding to the remaining progress block is obtained. Based on the optimized block length of the next progress block corresponding to the next construction cycle, the tunnel construction of the next progress block corresponding to the next construction cycle can be carried out to ensure the accuracy and rationality of the construction progress corresponding to each construction cycle, so as to facilitate construction supervision.

[0044] Please see Figure 2 The present invention also provides a method for monitoring the progress of tunnel construction, comprising: The tunnel design route is obtained through route acquisition unit 111; The tunnel geological model is obtained by model building unit 112 based on the tunnel design route and the geological exploration data corresponding to the tunnel design route; The tunnel geological model is divided into blocks by block division unit 113 to obtain multiple continuous progress blocks, each progress block corresponding to a construction cycle. After the tunnel construction process in the current construction cycle is completed by the risk monitoring unit 114, the construction risk of the current progress block is monitored based on the construction characteristic data of the current progress block corresponding to the current construction cycle, and the monitoring results are obtained. When the monitoring result of the first control output unit 115 indicates that there is no construction risk in the current progress block, the construction progress corresponding to the current progress block is completed, and tunnel construction continues according to the foundation block length of the next progress block corresponding to the next construction cycle; and When the monitoring result indicates that there is a construction risk in the current progress block, the second control output unit 116 optimizes the block length of the basic block of the next progress block corresponding to the next construction cycle based on the historical construction risk index corresponding to the historical construction cycle and the current construction risk index corresponding to the current progress block, so as to obtain the optimized block length and carry out tunnel construction of the next progress block corresponding to the next construction cycle through the optimized block length.

[0045] In summary, the tunnel construction progress monitoring system and method disclosed in this invention, by acquiring the tunnel design route corresponding to the spatial geometry of the tunnel to be constructed, and further combining it with geological exploration data obtained from actual exploration and surveying based on the tunnel design route, can further construct a tunnel geological model. This model can not only represent the spatial geometry but also the geological attributes related to the actual exploration. Then, based on the geological characteristics of the tunnel geological model, the model can be accurately divided into progress blocks to ensure that each progress interval meets a construction cycle. This allows for the quantification of tunnel construction progress in units of construction cycles, achieving not only the measurement of tunnel construction cycles but also quantitative monitoring of construction progress, thus improving construction efficiency. Furthermore, after initially determining the progress blocks, to ensure that the progress blocks remain consistent with actual construction and to reduce the risk of reduced tunnel construction quality due to excessively rapid construction, construction risk monitoring can be performed on the current progress block after each construction cycle is completed, using the construction characteristic data of the current progress block corresponding to the current construction cycle. When no construction risks exist, tunnel construction continues using the basic block length of the next progress block corresponding to the next construction cycle. However, if construction risks exist, historical construction risk indicators corresponding to previous construction cycles and current construction risk indicators corresponding to the current progress block can be comprehensively analyzed to optimize the basic block length of the next progress block corresponding to the next construction cycle. This optimized block length can then be used for tunnel construction in the next progress block of the next construction cycle. Furthermore, while optimizing the basic block length of the next progress block, the basic block lengths of the remaining progress blocks corresponding to other remaining construction cycles can also be optimized to achieve optimized monitoring of the entire construction progress through quantitative blocks. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
