Description

Technical Field

[0001] This invention belongs to the field of physical simulation technology of underground engineering rockburst, and particularly relates to a physical simulation test and monitoring method for fault slip rockburst. Background Technology

[0002] When carrying out underground engineering projects, disasters such as roof falls often occur in the rock mass surrounding the tunnel. In order to reduce the occurrence of disasters during construction and improve construction safety, physical models are constructed to simulate and study the stress and displacement of faults in underground engineering projects. This is of great significance for understanding the occurrence mechanism of various disasters in actual underground engineering projects.

[0003] The inventors discovered that current testing methods cannot effectively activate faults when conducting physical simulation tests of fault slip rockburst. Simply relying on impact force to activate faults often causes faults to appear in other parts of the test, affecting the test results, efficiency, and monitoring accuracy, which is not conducive to the study of underground engineering disasters. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a physical simulation test and monitoring method for fault slip rockburst. This invention weakens the rock mass strength near the fault through electrical activation, thereby improving the fault activation effect and ensuring test results and efficiency. Based on resistivity information, stress information, and thermal imaging information, the deformation of the model specimen and the degree of fault activation are determined, ensuring monitoring accuracy.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] This invention provides a physical simulation test and monitoring method for fault slip rockburst, comprising:

[0007] Fabricate a model specimen; within the model specimen, embed conductive materials according to predetermined positions, orientations, and directions;

[0008] The fabricated model specimen was subjected to a loading test. When the loading reached the point where the fault needed to be activated, an electric current was applied to the conductor to activate the fault.

[0009] Acquire resistivity, stress, and thermal imaging information of the model specimen during loading; based on the resistivity, stress, and thermal imaging information, determine the deformation and fault activation degree of the model specimen.

[0010] Furthermore, in the model specimen, the relative position between the tunnel and the fault structure is determined, and conductive copper wire mesh is pre-embedded at the location of the fault according to its dip and strike.

[0011] Furthermore, iron powder and mica flakes were added near the conductor in the model specimen.

[0012] Further, the model specimen fault is activated in a manner of mainly electric excitation and secondarily stress continuous loading in a slip zone.

[0013] Further, the model specimen is directly loaded by a preset primary loading oil cylinder, the loading plate acting on the surface of the model specimen is arranged on the primary loading oil cylinder, and the primary loading oil cylinder is compensated by a preset secondary loading device.

[0014] Further, when the loading plate is separated from the model specimen due to boundary instantaneous deformation between the model specimen and the primary loading oil cylinder, the secondary loading device directly compensates the primary loading oil cylinder, so that the primary loading oil cylinder and the model specimen remain in a loading state.

[0015] Further, a plurality of primary loading oil cylinders are arranged to load different regions of the model specimen, some of the primary loading oil cylinders in the slip zone are unloaded and withdrawn to provide a slip space for the fault, and the primary loading oil cylinder along the fault slip direction timely follows the loading force at the moment of fault slip and compensates.

[0016] Further, the fault weakening effect is adjusted by controlling the current intensity in the conductive body.

[0017] Further, the comprehensive evaluation index is determined according to the resistivity information, stress information and thermal imaging information, the deformation condition of the model specimen and the fault activation degree are determined according to the size of the comprehensive evaluation index, and the evaluation index is:

[0018] ;

[0019] Among them, is the resistivity at the current moment; is the resistivity at the previous moment; is the stress at the current moment; is the stress at the previous moment; is the time length used for the thermal imaging to change from uniformity to non-uniformity; is a preset time length; , and are weight coefficients; ,

[0020] and are initial values of , and , and When a sudden increase or decrease in resistivity, a sudden increase or decrease in force, or a change in thermal imaging from uniform to non-uniform all occur, and one or two of these indicators exceed their corresponding preset values, then the corresponding weighting coefficient is increased to maintain... + + =1 remains unchanged, corresponding to a preset value greater than the corresponding threshold; however, when all three evaluation indicators (first, second, and third) are greater than or less than their corresponding preset values, , and All use initial values , and .

[0021] Furthermore, by using support components with deformation-resistant properties, the surrounding rock at both ends of the fault is connected and formed into an anchored rock mass. Before the fault slips, the support components conform to Newton's first law, and the stress change characteristics of the support components are consistent with the stress change characteristics of the fault. During the fault slip, the slip characteristics conform to Newton's second law, and at this time, the stress of the support components rapidly decreases to a stable value. By measuring the stress and deformation characteristics on the support components, the stress and slip characteristics during fault slip are analyzed.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention embeds conductive bodies within a model specimen according to preset positions, inclinations, and orientations. A loading test is conducted on the fabricated model specimen. When the load reaches the point where fault activation is required, the conductive bodies are energized to activate the fault. This electrical activation weakens the rock mass strength near the fault, improving the test effect and efficiency. Based on resistivity, stress, and thermal imaging information, the deformation of the model specimen and the degree of fault activation are determined, ensuring monitoring accuracy and providing a favorable guarantee for the study of underground engineering disasters.

[0024] 2. During the fabrication of the model specimen of this invention, iron powder and mica flakes were added to the material near the fault simulation structure, which further weakened the strength of the rock mass near the fault and improved the fault activation effect.

[0025] 3. In this invention, when the loading plate separates from the model specimen due to instantaneous boundary deformation, the secondary loader directly compensates for the primary loading cylinder, keeping the primary loading cylinder and the model specimen under load and avoiding stress energy loss.

[0026] 4. In this invention, the fault weakening effect is adjusted by controlling the current intensity in the conductor, achieving the same degree of activation as the actual fault structure, thus improving the effectiveness and value of the experimental data. Attached Figure Description

[0028] Figure 1 This is a flowchart of Embodiment 1 of the present invention. Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Example 1:

[0032] like Figure 1 As shown, this embodiment provides a physical simulation test and monitoring method for fault slip rockburst, including:

[0033] S1. Determine the content of the physical simulation test for fault slip rockburst, including prefabricating high-impact-prone model specimens containing fault planes, and constructing a physical simulation test system capable of simulating fault slip rockburst.

[0034] S2. Determine the content of physical simulation monitoring of fault slip rock pressure, including real-time monitoring of fault status and real-time monitoring of surrounding rock status.

[0035] S3. Prefabricated high-impact-prone model specimens containing fault planes, including configuring simulation materials with high impact propensity, pre-setting fault simulation structures when casting test model specimens, and completing the rapid prototyping of simulated tunnels.

[0036] Understandably, configuring a simulation material with high impact susceptibility means adding such a material near the fault location on the model specimen. Optionally, a preset proportion of iron powder and mica flakes can be added to the conventional materials used to create the underground tunnel soil model to obtain a simulation material with high impact susceptibility. This high-impact-susceptibility simulation material is then added near the fault location on the model specimen.

[0037] When rapidly prototyping a simulated tunnel, one can optionally form a simulated tunnel in the model specimen by casting the model specimen and then excavating it in the shape of the specimen, or by pre-embedding a tunnel forming device during the casting process, or by reserving a tunnel in advance.

[0038] S4, a physical simulation test system capable of realizing fault slip rock burst simulation is constructed, including a loading system, capable of realizing partitioned sustained staged multi-gradient loading, capable of realizing local stable loading under disturbance state, and capable of realizing local sustained rapid loading under local load preservation condition; realizing local sustained rapid loading under local load preservation condition is used for assisting fault activation.

[0039] Optionally, in some embodiments, the loading system can be realized through a conventional test device; in other embodiments, a plurality of loading oil cylinders can be respectively arranged at each loading surface direction of the model test piece to construct the loading system. It can be understood that the loading system and the following monitoring device are both connected with a control system, which can realize data receiving, data processing and control function of related actions.

[0040] S5, real-time monitoring of fault state is determined, mainly including judging the overall and local deformation of the model test piece through the change of resistivity, judging the fault activation degree through the stress mutation of the fault slip monitoring device, and judging the local deformation of the model test piece through thermal imaging analysis.

[0041] It can be understood that the corresponding resistivity is different for different deformations of the model test piece, the relationship between the deformation of the model test piece and the resistivity can be fitted in advance according to historical data, so that the deformation of the model test piece can be directly obtained according to the resistivity during the test. The fault slip monitoring device can be provided at the monitoring position of the model test piece according to the requirement by using a force sensor. When thermal imaging analysis is performed, a thermal imager can be used to realize information acquisition and judgment.

[0042] S6, real-time monitoring of surrounding rock state is determined, mainly including real-time monitoring of surrounding rock stress by using a multi-directional stress monitoring device, real-time capture of the change of the preset point of the roadway by using digital photography technology to judge the displacement of the roadway surrounding rock, and real-time monitoring of the dynamic change of the support stress by using a support stress monitoring device.

[0043] The embodiment realizes fault slip rock burst physical simulation test and fault slip rock burst early warning monitoring. In the model test piece, the conductive body is pre-buried according to the preset position, inclination and trend; the model test piece after being made is subjected to loading test, and when the fault needs to be activated, the conductive body is electrified to activate the fault; the strength of the rock mass near the fault is weakened through electric activation, the test effect and test efficiency are improved, the deformation of the model test piece and the fault activation degree are judged according to the resistivity information, stress information and thermal imaging information, the monitoring accuracy is ensured, and favorable guarantee is provided for the research on underground engineering disasters.

[0044] Optionally, in terms of resistivity information: when the model specimen is stressed, the model specimen will deform, and the resistivity will change; when the loading is stable, the resistivity is stable; therefore, before the fault is activated, the resistivity is fixed, and during the fault activation process, the resistivity will have a sudden increase or decrease, which is the first evaluation index for judging deformation and fault activation. In terms of stress information: the principle is the same as above, and the collected stress information will change; however, in order to avoid the influence of external factors such as voltage, mutual verification is required; during the fault activation process, the stress size will have a sudden increase or decrease, which is the second evaluation index for judging deformation and fault activation. In terms of thermal imaging: before the fault slips, due to the change in strength near the fault, the model specimen will have a slip trend, causing the surface to have thermal imaging from uniform to non-uniform change, which is the third evaluation index for judging deformation and fault activation, which can be represented by time length.

[0045] The three phenomena of sudden increase or decrease of resistivity, sudden increase or decrease of stress size, and thermal imaging from uniform to non-uniform change occur simultaneously, or two of them, or one of them is more prominent, can be judged, and the three phenomena are mutually verified.

[0046] In some embodiments, the determination of the comprehensive evaluation index can be made by weighted fusion, for example, the comprehensive evaluation index is:

[0047] ;

[0048] wherein, is the resistivity at the current time; is the resistivity at the previous time; is the time interval between the current time and the previous time, which can be pre-set; is the stress size at the current time; is the stress size at the previous time; is the time length for thermal imaging from uniform to non-uniform change; is the preset time length, which can be obtained by the average of the time length of each occurrence of uniform to non-uniform change in historical experiments; , and are weight coefficients; optionally, when at least one of the phenomena of sudden increase or decrease of resistivity, sudden increase or decrease of stress size, and thermal imaging from uniform to non-uniform change occurs, there is a relationship of + + =1, and the phenomenon that does not occur corresponds to a weight coefficient of 0.

[0049] In other embodiments,​​​ , and The initial values of , and When the resistivity increases or decreases suddenly, the force increases or decreases suddenly, and the thermal imaging changes from uniform to non-uniform, that is, when the first evaluation index , the second evaluation index and the third evaluation index all appear greater than the corresponding threshold value, and one or two of them are greater than the corresponding preset value, then the corresponding weight coefficient is increased, and + + =1 remains unchanged, the corresponding preset value is greater than the corresponding threshold value; when the three first evaluation indexes, second evaluation indexes and third evaluation indexes are all greater than the corresponding preset value, or all less than the corresponding preset value, , and all adopt the initial values , and ; by adjusting the weight coefficients of the first evaluation index, the second evaluation index and the third evaluation index in real time, the accuracy of judging the deformation of the model specimen and the degree of fault activation can be improved.

[0050] Optionally, the deformation of the model specimen and the degree of fault activation can be determined according to the size of the comprehensive evaluation index .

[0051] In some embodiments, optionally, a fault simulation structure is pre-prepared in the model specimen, combined with the relative position of the underground engineering and the fault, according to the inclination, strike, angle and width of the fault, a fault simulation structure is pre-prepared in the model specimen, and the specific process of making the model specimen containing the fault includes:

[0052] S3.1, determine the relative position between the roadway and the fault simulation structure; at the position of the fault, arrange the conductive body according to the inclination and strike, and the conductive body is optionally a conductive copper wire mesh;

[0053] S3.2, in the process of making the model specimen, use a material with high impact tendency, combined with the width of the fault and the strength of the fault surface, use a material with high impact tendency added with auxiliary materials such as iron powder and mica sheet near the conductive copper wire mesh to make the fault simulation structure;

[0054] In the process of making the model specimen, iron powder and mica sheet are added to the material near the fault simulation structure to weaken the strength of the material near the fault simulation structure.

[0055] S3.3, the fault is activated by mainly using electric excitation and secondarily using high stress sustained loading in the slip zone.

[0056] In the model specimen test process, when the fault needs to be activated, the copper wire mesh is further weakened in strength near the rock mass by electrifying the conductive copper wire mesh, so as to achieve the purpose of activating the fault. Alternatively, the weakening effect of the fault is achieved by controlling the current intensity, so as to achieve the same purpose as the actual fault structure activation degree.

[0057] In some embodiments, in order to ensure that the fault structure activation degree of the model specimen in the test is the same as the actual fault structure activation degree, the current intensity is adjusted in real time during the test. Alternatively, in the historical data, the stress information and deformation information related to the actual fault structure activation degree, or the stress information and deformation information obtained in the test, are fitted with time as the horizontal coordinate and the stress information and deformation information as the vertical coordinate. After fitting the stress information and deformation information related to the actual fault structure activation degree, the scaling is performed according to the proportion between the test data, so as to achieve the purpose of the coordinate value corresponding to the test data fitting. During the test, the real-time monitored deformation and stress are compared with the deformation and stress corresponding to the same time in the fitting data. When the difference between the actual monitored deformation or stress and the deformation or stress in the fitting data is greater than the preset difference value within a certain time range, the current intensity is adjusted until the difference between the actual monitored deformation or stress and the deformation or stress in the fitting data is within the preset difference value.

[0058] It can be understood that the difference between the actual monitored deformation and the deformation in the fitting data includes negative and positive values, and the comparison is the absolute value when compared with the preset difference value. When the difference between the actual monitored deformation and the deformation in the fitting data is negative and the absolute value is greater than the preset difference value, the current intensity is increased. When the difference between the actual monitored deformation and the deformation in the fitting data is positive and greater than the preset difference value, the current intensity is decreased. Similarly, the difference between the actual monitored stress and the stress in the fitting data includes negative and positive values, and the comparison is the absolute value when compared with the preset difference value. When the difference between the actual monitored stress and the stress in the fitting data is negative and the absolute value is greater than the preset difference value, the current intensity is increased. When the difference between the actual monitored stress and the stress in the fitting data is positive and greater than the preset difference value, the current intensity is decreased.

[0059] Alternatively, in the test process, the slip zone is continuously loaded with high stress, and the other parts are stably and constantly loaded, so as to achieve auxiliary activation of the fault.

[0060] Optionally, in the process of casting the model test piece from bottom to top, the flowability of the material in a certain distance below will decrease after casting a certain depth, so the fault is made later than the model test piece. According to the engineering profile of the strike, tendency and dip angle of the fault, the low-flowability area at the corresponding position is laid with materials such as mica sheet and iron powder by using auxiliary devices to reduce the strength of the rock mass at the fault position and form a weak plane.

[0061] The embodiment realizes the preparation of the prefabricated fault simulation structure and the activation of the fault in the test process.

[0062] In some embodiments, a preset primary loading oil cylinder is used to directly load the model test piece, a loading plate acting on the surface of the model test piece is arranged on the primary loading oil cylinder, and a preset secondary loader is used to compensate the primary loading oil cylinder. Both the primary loading oil cylinder and the secondary loader can be realized by a conventional loading device, which will not be described in detail here.

[0063] Specifically, when the loading plate is separated from the model test piece due to the instantaneous deformation of the boundary between the model test piece and the primary loading oil cylinder, the secondary loader directly compensates the primary loading oil cylinder to timely maintain the loading state between the primary loading oil cylinder and the model test piece, avoiding the loss of stress energy. The secondary loader can be excited by electric induction or high-pressure gas induction.

[0064] The preset multiple primary loading oil cylinders load different areas of the model test piece, some of the primary loading oil cylinders in the slip area are unloaded and withdrawn to provide a slip space for the fault, and the primary loading oil cylinders in the direction of fault slip timely follow up the loading force and compensate at the moment of fault slip.

[0065] In some embodiments, under the condition of local constant loading, local continuous and rapid loading is used to assist the activation of the fault and carry out the physical simulation test of fault slip rockburst; by locally and rapidly unloading the loading surface that hinders the fault slip and rapidly compensating and loading the loading surface in the direction of fault slip, the fault slip simulation is realized.

[0066] Optionally, the loading surface that hinders the fault slip needs to be judged according to the actual fault slip area; some of the loading oil cylinders in the slip area are rapidly unloaded and quickly withdrawn to provide a slip space for the fault. The loading surface in the direction of fault slip needs to timely follow up the loading force and compensate at the moment of fault slip to avoid the problems of slow loading, stress unloading and energy early release, and inability to restore the characteristics of rockburst.

[0067] In some embodiments, the force generated before fault slip is measured by supporting members capable of bearing large deformation; the supporting members connect the surrounding rock on both sides of the fault and form an anchored rock mass as anchoring members. Before fault slip, the supporting members comply with Newton's first law, and the stress change characteristics of the supporting members are consistent with the stress change characteristics of the fault. During fault slip, the slip characteristics comply with Newton's second law, and the stress of the supporting members will rapidly decrease to a stable value. By measuring the stress and deformation characteristics of the supporting members, the stress and slip characteristics during fault slip can be analyzed.

[0068] In some embodiments, the anchoring members are installed by profiling excavation after the model test piece is cast, or by pre-embedding a roadway forming device during casting, or by reserving a roadway, to form a simulated roadway in the model test piece. A borehole is drilled from the surface of the roadway in the vertical direction of the fault, through the fault, and then the anchoring members are installed to change the simulated natural rock mass into a simulated anchored rock mass.

[0069] In some embodiments, for the model test piece with a profiled excavation roadway and the model test piece with a pre-embedded roadway forming device, the roadway can be formed before loading the model test piece or after applying the equivalent initial ground stress, according to the test requirements.

[0070] Optionally, the drilling direction is determined according to the relative position of the fault and the roadway, and the drilling direction can form a certain angle with the fault structure surface, which can be selected from 60° to 90°. The anchoring end of the anchoring member needs to pass through the fault, and the anchoring method can be mechanical anchoring or cementing agent anchoring. The anchoring member needs to use a material with large deformation characteristics, which can not be broken at the initial stage of fault slip to avoid the failure of monitoring data to reflect the fault slip characteristics.

[0071] In some embodiments, dynamic stress monitoring elements are installed at the exposed end of the anchoring member, and the stress and deformation of the anchored rock mass are monitored to monitor the stress and slip characteristics of the fault.

[0072] In some embodiments, dynamic stress monitoring is installed at the exposed end of the anchoring member, and high pre-tightening force is applied. The application effect of the pre-stress is monitored by the dynamic stress monitoring elements, and the stress characteristics during the entire fault slip process are monitored.

[0073] The above only describes the preferred embodiments of the present embodiment and is not intended to limit the present embodiment. For those skilled in the art, the present embodiment can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present embodiment shall be included in the protection scope of the present embodiment.
