Description

Technical Field

[0001] The present application relates to the field of dynamic analysis technology, and in particular to a method, device, computer equipment, storage medium and computer program product for dynamic analysis of hard rock slope block stability of a highway. Background Art

[0002] Dynamic analysis of hard rock slope stability on highways is a complex and important geotechnical engineering problem, which involves many aspects such as the geometric characteristics of the slope, the physical and mechanical properties of the rock, the action of groundwater, climatic conditions, and external loads.

[0003] At the same time, stereographic projection within the base circle is widely used in engineering geological analysis. Its principle is to project the plane and straight line in the three-dimensional space into a section of an arc or a point within the equatorial circle on the two-dimensional plane, analyze the relative position relationship of these arcs, and judge whether an unstable block can be formed. This is called the traditional stereographic projection method. At present, in the "Specifications for Slope Design of Water Conservancy and Hydropower Engineering" (SL386-2007), "Technical Specifications for Slope Engineering of Buildings" (GB 50330-2013), "Engineering Geology Manual" and other specifications and reference books, stereographic projection (projection within the equatorial circle) is used as an analysis tool for the stability of blocks formed by structural surface cutting on hard rock slopes of highways. However, this analysis method is not intuitive for the judgment of movable blocks and key blocks, and is prone to misjudgment and omission. In addition, it is impossible to give the instability mode of the joint cone and cannot fully and completely identify various types of key blocks, so the analysis results are not accurate.

[0004] Therefore, there is an urgent need for an accurate dynamic analysis method for the stability of hard rock slope blocks on highways. Summary of the invention

[0073] In one embodiment, Figure 2 As shown in the figure, a dynamic analysis method for the stability of hard rock slope blocks on highways is provided. Figure 1 Taking the server 104 in the example as an example, the following steps are included:

[0074] S100: Obtain engineering survey data of hard rock slopes on highways and construct slope models.

[0075] Conduct on-site surveys on the hard rock slope engineering of the highway and record key information such as the rock type, joints and fissures, weathering conditions, groundwater conditions, etc. of the slope. According to the specific conditions of the slope, select appropriate measuring instruments, such as total stations, GPS-RTK, 3D laser scanners, or drone aerial survey and aerial photography technology, to accurately measure the slope. The engineering survey data of the hard rock slope of the entire highway is obtained through the above-mentioned geological surveys and topographic measurements. According to actual needs, select appropriate modeling software, such as AutoCAD, SketchUp, Revit, etc., to build a three-dimensional model of the slope. Based on the geological survey data and topographic survey data, a three-dimensional model of the slope is constructed in the modeling software. The model should accurately reflect the geometric shape, rock distribution, structural characteristics, etc. of the slope. Specific slope models such as Figure 3 Furthermore, after obtaining the engineering survey data of the hard rock slope of the highway, a geological attribute database can be established for further analysis and verification in subsequent processing.

[0076] S200: Statistical analysis of structural surface development characteristics based on engineering survey data and slope models.

[0077] According to the survey data, the development characteristics of the structural surfaces in the study area are statistically analyzed and grouped. Specifically, the development characteristics of the structural surface include multiple dimensional characteristics, such as the type, scale, occurrence (dip and inclination), roughness, opening, fillings, number of joints, etc. of the structural surface. Based on the engineering survey data and slope models, the influence of the development characteristics of the structural surface on the stability of the slope can be statistically analyzed by means of numerical simulation and physical model tests. These models can help engineers better understand the deformation and failure mechanism of the slope and provide a scientific basis for slope support design. In practical applications, the statistical analysis of the development characteristics of the structural surface is obtained, such as Figure 4 shown.

[0078] S300: Identify key blocks based on the structural surface development characteristics and input calculation parameters, and predict local slope stability problems caused by the instability of key blocks during construction, and generate support measures and recommended data corresponding to the local slope stability problems.

[0079] The user inputs a variety of calculation parameters collected, and the server identifies key blocks based on the structural surface development characteristics and the input calculation parameters, predicts the local stability of the slope of key blocks (not located blocks) during the actual construction process, and proposes corresponding support measures and recommended data. Use the structural surface information (such as type, scale, occurrence, roughness, opening, filling, etc.) in the engineering survey data to build a detailed structural surface network in the slope model. Analyze the intersection relationship between structural surfaces and identify the structural surface combination that may form key blocks. Apply block theory (such as stereographic projection method, block limit equilibrium method, etc.) to analyze the structural surface network and identify key blocks that may be unstable. Evaluate the volume, shape, weight and stability of key blocks to determine the disturbances and stress changes they may be subjected to during construction. Simulate the stress redistribution inside the slope during construction and evaluate the impact of excavation on the stability of key blocks. Consider the impact of factors such as excavation unloading and unloading rebound on slope stress, and predict possible local failure modes (such as sliding, dumping, falling, etc.). Analyze the impact of external factors such as rainfall and earthquakes on slope stability, and evaluate how these factors aggravate or induce the instability of key blocks. Consider the impact of groundwater on the strength of structural surfaces, especially those with large openings, which may form sliding surfaces under the action of groundwater. Design a reasonable support plan for the predicted local stability problems of the slope. Support measures may include anchor rods, anchor cables, anti-slide piles, retaining walls, etc. The specific selection needs to be considered comprehensively based on factors such as the geological conditions, failure mode and economy of the slope. Design support parameters, such as the length, diameter, inclination, and spacing of anchor rods or anchor cables, to ensure that the support structure can effectively constrain the movement of key blocks. Propose detailed construction steps and precautions to ensure that the support structure can be accurately constructed according to design requirements. Emphasize the monitoring and feedback mechanism during the construction process to promptly detect and deal with problems in construction.

[0080] S400: Perform semi-positioned block analysis on the slope based on engineering survey data combined with geological structural factors, and generate support measures and recommended data corresponding to the semi-positioned block analysis.

[0081] Collect engineering survey data of the slope, including geological survey reports, topographic survey data, rock mechanics parameters, etc. Record in detail the type, scale, occurrence (dip and inclination), roughness, opening, filling and other characteristics of the structural surface in the slope. In the slope model, a detailed structural surface network is constructed based on the collected structural surface information. This helps to understand the structural characteristics and potential instability factors inside the slope. Apply block theory (such as stereographic projection method, block limit equilibrium method, etc.) to analyze the structural surface network and identify the structural surface combination that may form the key block. Therefore, semi-positioned block analysis is used, that is, to determine the approximate location and range of the block. Evaluate the stability of the block, considering its stress state and potential failure mode under natural conditions. Further, in the process of semi-positioned block analysis, semi-positioned block analysis can be performed on the proven faults, fractures, joint-intensive zones and structural fracture zones of the slope based on engineering survey data combined with geological structural factors.

[0082] S500: Based on the development characteristics of the structural surface, random joint parameters are set for the overall stability of the slope, and the progressive instability process of the slope is analyzed using three-dimensional cutting to generate support measures and recommended data corresponding to the progressive instability process of the slope.

[0083] According to the development characteristics of the structural surface in the engineering survey data, the statistical distribution law of the joint parameters (such as normal distribution, lognormal distribution, etc.) is determined, and a random number generator is used to generate a series of random joint parameter values ​​under the constraints of the statistical distribution law. The joint parameters specifically include attitude, spacing, roughness, opening, and filling. Based on the previously constructed slope model, three-dimensional cutting is used to analyze the progressive instability process of the slope. Specifically, the three-dimensional cutting technology is used to cut the slope model in different directions to observe and analyze the stress distribution and deformation inside the slope, simulate the progressive instability process of the slope under the action of external factors such as excavation, rainfall, and earthquakes, and observe the failure mode and instability path of the slope. Finally, based on the analysis results, the support measures and recommended data corresponding to the progressive instability process of the slope are generated.

[0084] The above non-positioned block analysis only focuses on the stability of local slopes. Here, based on the results of previous survey data and combined with structural factors, random structural surface parameters are set, structural surface network simulation and block search are carried out, and three-dimensional block cutting and progressive instability analysis and calculation of non-positioned blocks and random blocks are used to study the overall stability of the slope.

[0085] In actual application, the results of three-dimensional block cutting analysis for sample 1, sample 2, sample 3, and sample 4 are as follows Figure 5 The corresponding progressive instability analysis results are shown in Figure 6 The final results of the progressive instability analysis of different sample block systems of the slope are shown in Table 1.

[0086] Table 1 shows the results of the progressive instability analysis of different sample block systems of the slope

[0087]

[0088] S600: During the construction phase, the slope is positioned and analyzed based on the structural surface information actually revealed during the construction process. The differences between the results and the slope stability problems are compared, the rock support design plan is verified, and adjustment suggestion data is generated.

[0089] During the construction process, based on the actual exposed structural surface information, the slope is positioned and block analysis is carried out, and the differences in the predicted results before excavation are compared. The rock support design plan is checked and adjustment suggestions are made.

[0090] The above-mentioned dynamic analysis method for block stability of hard rock slopes of expressways obtains engineering survey data of hard rock slopes of expressways and constructs a slope model; based on the engineering survey data and the slope model, statistically analyzes the development characteristics of structural surfaces; identifies key blocks according to the development characteristics of structural surfaces and the input calculation parameters, and predicts the local stability problem of the slope caused by the instability of key blocks during construction, and generates support measures and recommended data corresponding to the local stability problem of the slope; performs semi-positioned block analysis on the slope based on the engineering survey data combined with geological structural factors, and generates support measures and recommended data corresponding to the semi-positioned block analysis; sets random joint parameters for the overall stability problem of the slope based on the development characteristics of structural surfaces, uses three-dimensional cutting to analyze the progressive instability process of the slope, and generates support measures and recommended data corresponding to the progressive instability process of the slope; performs positioned block analysis on the slope based on the actual structural surface information revealed during the construction process, compares the difference between the results and the local stability problem of the slope, verifies the rock support design plan and generates adjustment recommendation data. During the whole process, combined with the development characteristics of the structural surface of the hard rock slope of the highway, the block theory, three-dimensional block cutting, and block progressive instability analysis are used to form a dynamic analysis of the stability of deterministic structural surfaces, key blocks, semi-positioned blocks, and positioned blocks during the entire process of highway slope construction, which can achieve accurate dynamic analysis of the stability of hard rock slope blocks on highways.

[0091] like Figure 7 As shown, in one embodiment, S200 includes:

[0092] S220: Structural surfaces are divided into different levels based on engineering survey data and slope models and in reference to preset industry specifications.

[0093] First, structural surfaces are divided into different levels according to geological types, mechanical properties and the impact on rock mass stability. Generally speaking, structural surfaces can be divided into five levels (level I to level V), each of which has its own specific characteristics: Level I: Extends for tens of kilometers, can cut through a structural layer in depth, and the width of the broken zone is tens of meters to less than ten meters. This type of structural surface is a weak structural surface, which has a significant impact on regional stability and mountain stability. Level II: Extends from hundreds of meters to several kilometers, and the width of the broken zone is narrow, from a few centimeters to several meters. Mainly including unconformity surfaces, pseudo-conformity surfaces, primary weak interlayers, etc., are also weak structural surfaces, which have a controlling effect on mountain stability. Level III: Extends for ten meters or tens of meters, without a broken zone, may not contain mud or have mud film in the surface, and the distribution is relatively limited. Most of these structural surfaces are hard structural surfaces, and a few are weak structural surfaces, which have an important impact on the stability of the rock mass. Level IV: Extends for several meters, has no displacement, no mud, and some are in a weakly bonded state, such as bedding, unloading cracks, etc. This type of structural surface is mostly hard, and combined with other structural surfaces, it can form different types of slope failure modes. Grade V: Very poor continuity, small or subtle cracks in rigid contact, such as micro joints, subtle cracks, etc. This type of structural surface is randomly distributed, which will reduce the strength of the rock block and is the basis of the effect of rock mechanical properties. Further, the preset industry specifications here can be specifically the "Geotechnical Engineering Investigation Specifications".

[0094] S240: Analyze the development scale, distribution range and occurrence characteristics of structural surfaces of different levels to obtain the development characteristics of the structural surfaces.

[0095] Developmental scale

[0096] Level I: large in scale, extending over a long distance, often spanning multiple geological structural units. Level II: second in scale, but also distributed continuously over a large area. Level III: smaller in scale, mainly distributed in one geological era or lithology. Levels IV and V: smaller in scale, usually confined to a local area, and in a tiny or hidden state.

[0097] Distribution

[0098] Levels I and II: Widely distributed in the project area, may have a significant impact on the overall stability. Level III: Distributed in specific geological units or lithology, has an important impact on local stability. Levels IV and V: More localized, but have a significant impact on the mechanical properties of the rock.

[0099] Occurrence characteristics

[0100] Strike and inclination: record the strike and inclination of each level of structural surface. These parameters are crucial for judging the stability of the slope. Inclination: measure the inclination of each level of structural surface. Structural surfaces with different inclinations have different effects on slope stability. Combination relationship: analyze the combination relationship between structural surfaces, such as parallel, cross, conjugate, etc. These combination relationships have an important influence on the failure mode of the slope.

[0101] Through the above analysis, the development characteristics of the structural plane can be obtained, including its grade, scale, distribution range and occurrence characteristics. These characteristics are of great significance for understanding the rock structure of the slope, predicting potential failure modes and formulating reasonable engineering measures.

[0102] In one embodiment, identifying key blocks based on structural surface development characteristics and input calculation parameters includes: based on the structural surface development characteristics, randomly combining dominantly developed structural surfaces to determine unpositioned blocks; and identifying key blocks formed on different free-facing surfaces based on the unpositioned blocks and input calculation parameters.

[0103] After the structural surfaces are grouped, the unpositioned blocks in different combinations are analyzed to identify the key blocks formed on different free-facing surfaces. Specifically, unpositioned blocks (or movable blocks) refer to those rock blocks that may move relative to each other under the action of gravity or other external forces due to the existence of structural surfaces. The boundaries of these blocks are defined by structural surfaces (such as joints, faults, layers, etc.). Key blocks refer to those rock blocks in unpositioned blocks that are more likely to become unstable or slide due to specific free-facing surface conditions (such as slope surfaces, river valley surfaces, etc.). According to the actual conditions of the project site, determine the slope or other areas where free-facing surfaces may be formed. Project the unpositioned blocks onto each free-facing surface and analyze the shape, size and stability of the blocks on the free-facing surface. Combined with the input calculation parameters (such as rock mass mechanical parameters, external load conditions, etc.), evaluate the stability of the blocks on the free-facing surface. If the stability of a block on a specific free-facing surface is extremely poor and its instability may have a significant impact on the overall stability of the slope, the block is considered a key block.

[0104] In one embodiment, according to the unpositioned blocks and the input calculation parameters, identifying the key blocks formed on different free-side surfaces includes:

[0105] According to the unpositioned blocks and the input calculation parameters, the full-space stereographic projection diagram is generated by using block theory engineering analysis software. The solid lines in the full-space stereographic projection diagram represent the projection of the structural surface, the dotted lines represent the projection of the free surface, and the central dotted circle is the base circle; the 8 joint cone spaces in the full-space stereographic projection diagram that are mutually cut by the solid lines, as well as the excavation cone and space cone formed by the free surface dotted lines cutting the solid space are identified; the joint cone located in the space cone is determined to be a movable block; the movable block with a safety factor less than 1 is determined to be a key block according to the input calculation parameters.

[0106] The full-space stereographic projection diagram (such as Figure 8As shown in the figure, the solid line represents the projection of the structural surface, the dotted line represents the projection of the free surface, and the central dotted circle is the base circle. The solid lines cut each other to divide the solid space into 8 joint cone spaces, while the dotted line of the free surface divides the solid space into two, namely the rock space - the excavation cone and the non-rock space - the space cone. According to the mobility theorem, when the joint cone is completely located in the space cone, the joint cone is movable, and it can be determined as a movable block. Movable blocks with a safety factor less than 1 can be determined as key blocks. In the full-space stereographic projection diagram, after determining the movable key blocks according to the mobility theorem, the built-in programming software can be visualized in three dimensions to show the shape of the blocks on the slope. The location and morphological characteristics of the blocks can be displayed more intuitively, which is convenient for further support analysis during engineering analysis.

[0107] In one embodiment, during the construction process, local slope stability problems caused by instability of key blocks during the construction process are predicted, and support measures and recommended data corresponding to the local slope stability problems are generated, including:

[0108] According to the input calculation parameters, the free surface area, maximum depth and block distribution density of the key blocks are calculated; the safety factor and required support force are calculated using the support analysis software based on the free surface area, maximum depth and block distribution density; based on the safety factor and required support force, support measures and recommended data are generated.

[0109] The selection of support measures and methods needs to comprehensively consider the small free surface area of ​​the key block, the maximum depth and the distribution density of the block. Using the support analysis software, calculate the safety factor k0 (safety margin), k c (bearing capacity safety factor), and required support force, etc. Based on the above analysis, corresponding support measures and suggestions are formulated to ensure the safety of the project. Specifically, the stability of the slope blocks is shown in Table 2 below, and the required anchoring force of the key blocks is shown in Table 3 below.

[0111]

[0112] Table 3 shows the anchoring force required for key blocks

[0113]

[0114] In one of the embodiments, random joint parameters are set for the overall stability problem of the slope based on the development characteristics of the structural surface, and the progressive instability process of the slope is analyzed by three-dimensional cutting. Support measures and recommended data corresponding to the progressive instability process of the slope are generated, including: setting random joint parameters for the overall stability problem of the slope based on the development characteristics of the structural surface to perform structural surface network simulation and block search; analyzing the overall stability of the slope during the progressive instability process by using three-dimensional block cutting and progressive instability analysis and calculation of unlocated blocks and random blocks; and generating support measures and recommended data corresponding to the progressive instability process of the slope based on the overall stability analysis results.

[0115] The unlocated block analysis only focuses on the stability of local slopes. Based on the results of previous survey data and combined with structural factors, random structural surface parameters are set, structural surface network simulation and block search are carried out, and the overall stability of the slope is studied by using three-dimensional block cutting and progressive instability analysis and calculation of unlocated blocks and random blocks.

[0116] Specifically, according to the characteristics of structural plane development in geological data, the random joint parameters are set using the Monte-Carlo random simulation principle. These parameters should include the occurrence (strike, dip, inclination), trace length, spacing, density, etc. of the joints. The statistical laws of these parameters are obtained through random sampling, random transformation, normalization, and other methods, and a structural plane network model (DFN) is constructed. The random joint parameters are applied to the slope area using the three-dimensional discrete structural plane network simulation technology to construct a three-dimensional structural plane network model of the slope. Through this model, the distribution of structural planes inside the slope can be intuitively displayed, laying the foundation for subsequent block search and analysis. Based on the structural plane network model, the three-dimensional random key block search algorithm is used to identify potential unstable blocks in the slope. These blocks may be in an unstable state due to the cutting effect of the structural plane. The searched blocks are numbered and classified for subsequent analysis and processing. The slope is virtually cut using three-dimensional cutting technology to simulate the deformation and failure process of the slope under different conditions. During the cutting process, the focus is on the cutting effect of the structural surface on the blocks and the interaction between the blocks; based on the three-dimensional block cutting results, the progressive instability analysis of the slope is carried out. During the analysis, the deformation and failure process of the slope under different external conditions (such as rainfall, earthquake, blasting, etc.) are considered. Using numerical analysis methods (such as discrete element method, finite element method, etc.), the stress, strain and displacement parameters of the slope at different stages are calculated to analyze the overall stability of the slope; special attention is paid to those blocks that are not fixed in position (unpositioned blocks) and randomly appearing blocks (random blocks) during the progressive instability process. These blocks may have an important impact on the overall stability of the slope. The movement laws, failure modes and degree of influence of these blocks on the overall stability of the slope are analyzed; the progressive instability process of the slope and its overall stability evaluation results are comprehensively analyzed to determine the potential danger areas and main instability modes of the slope; based on the results of the overall stability analysis, targeted support measures are formulated.

[0117] In general, in the dynamic analysis method of the stability of hard rock slope blocks on highways in this application, analysis is performed before excavation and during excavation. The analysis before excavation of the slope includes the following contents:

[0118] Collect detailed geological data of the slope area, including rock type, distribution of structural surfaces (such as joints, fissures, faults, etc.), occurrence, trace length, density and other parameters. Preprocess the data, including cleaning invalid data and data standardization, to ensure the accuracy of subsequent analysis.

[0119] ① Analysis of local slope stability

[0120] a) Analyze the characteristics of structural surface development based on the survey data, analyze and predict the stability and instability mode of local unlocated blocks in the slope under different combined cutting; identify key blocks without considering cohesion;

[0121] b) Analyze the size and morphological characteristics of the unlocated blocks, determine the key blocks that need to be supported and formulate corresponding support measures;

[0122] c) Combined with geological structural factors, analyze whether the structural joint group and random structural surface can form a semi-positioned block, as well as the mobility, instability mode and geometric form of the block, determine the required support force, and formulate block support measures;

[0123] d) Based on the analysis results, it is advisable to make recommendations on the engineering design scheme (such as the slope direction and slope of the free surface of the slope, the axial direction of the underground cavern, etc.);

[0124] ②Analysis of overall slope stability

[0125] a) When the investigation conditions permit, it is advisable to conduct on-site statistical investigation and analysis of the structural surface, three-dimensional structural surface network simulation, random block analysis or three-dimensional block cutting analysis; it is advisable to conduct a predictive analysis of the geometric characteristics of the random blocks and the required support force, and make recommendations on the support parameters such as the anchoring support force and anchoring length required for the blocks based on the analysis results.

[0126] ③Special measures

[0127] a) For important engineering parts, statistical analysis of the differences in structural surface development characteristics should be conducted based on the survey results of different engineering sections. When significant differences exist, analysis should be conducted in different sections;

[0128] b) If exploration reveals multiple intersecting positioning structural surfaces, it should be analyzed whether a positioning block can be formed, as well as the mobility, instability mode and geometric shape of the block.

[0129] (2) Analysis during slope construction

[0130] The construction phase mainly involves the analysis of positioning blocks and the review of block prediction analysis and support measures in the survey and design phase. The main work should include:

[0131] a) According to the development characteristics of the structural surface actually exposed after rock mass excavation, geological records are made on the exposed position, occurrence, trace length, etc. of the structural surface;

[0132] b) Conduct block identification analysis based on the geological logging results of the structural surface;

[0133] c) Compare the differences between the geometric features of the structural surface actually exposed and those in the survey and design stage. If the differences are large, the block analysis results in the survey and design stage should be reviewed again, and suggestions for support design adjustments should be made if necessary;

[0134] d) When a new or extended structural surface is revealed that exceeds the scale known in the survey and design stage, the intersection of multiple adjacent structural surfaces should be analyzed to analyze whether it can be closed and cut to form a block, and the stability and support analysis of the block should be carried out;

[0135] e) Check the rock support design plan in a timely manner and make adjustment suggestions based on the analysis results to ensure effective reinforcement of larger positioning blocks that may become unstable;

[0136] f) When a long structural surface that may form a block needs to go through multiple excavation stages before it can be fully exposed, it is advisable to conduct additional surveys on the extension and properties of the structural surface. In the next stage of excavation, the geological sketch results of the structural surface should be compared with the previous stage to determine the connectivity of the structural surface exposed in the current stage with that in the previous stage. From a safety perspective, it should be assumed that the structural surface extends long enough and a block analysis should be conducted. Based on the analysis results, support should be implemented in a timely manner for the exposed blocks, and then subsequent construction excavation should be carried out.
