[0035] The embodiments of the present application provide a deep underground cavern support assessment method and system based on disturbance energy, which can solve the problem that the on-site anchor rod / anchor cable system support structure fails to be set up in time or is improperly applied, releasing additional disturbance energy, thereby causing local stress concentration, severe deformation, and even geological disasters such as landslides and rock bursts.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0037] See also Figure 1 , which is a flow chart of a deep underground cavern support assessment method based on disturbance energy provided in an embodiment of the present application, and may specifically include: S110-S130.

[0038] S110, determining the initial support point distribution information of the initial support scheme based on the initial ground stress field, so as to evaluate the independent impact characteristics of each initial support point on the surrounding rock when performing support drilling and the associated impact characteristics of multiple initial support points on the surrounding rock when performing support drilling at the same time.

[0039] S120, determining a support drilling simulation scheme similar to the mechanical excavation disturbance based on the independent influencing features and the associated influencing features, wherein the support drilling simulation scheme includes drilling position distribution and drilling depth.

[0040] S130, monitoring actual disturbance information during the execution of the support drilling simulation scheme to optimize the initial support scheme based on the actual disturbance information.

[0041] It is understandable that the drilling and anchor installation during support setting will cause disturbances to the surrounding rock, which simulates the stress redistribution caused by cutterhead cutting and vibration in mechanical excavation in a local range. Both involve stress release, disturbance energy transfer and crack expansion of the surrounding rock. The scale and energy of support disturbance are usually smaller than those of mechanical excavation, but through the synchronous operation of multiple support points and the disturbance superposition effect, it can be as close as possible to the comprehensive disturbance effect of mechanical excavation on the surrounding rock. The disturbance energy of drilling and anchor setting is quantified through monitoring data, including stress release, vibration frequency and crack expansion. For example, when the drilling depth is 4 meters, monitoring found that the local stress release is 0.8MPa and the crack expansion is about 1.5 meters. Through simultaneous drilling at multiple support points, the stress change and energy release characteristics of the surrounding rock under the synchronous action of multiple cutter heads during mechanical excavation are simulated. For example, when three support points are operated simultaneously, the disturbance radius increases to 3 meters, and the cumulative stress release is 2.5MPa. Analyze the propagation range, energy attenuation and crack distribution pattern of support disturbance, and infer the propagation path and possible impact range of mechanical excavation disturbance energy. For example, the drilling disturbance energy is concentrated at the top of the excavation area, and the priority direction of top crack expansion during mechanical excavation is predicted. By recording the entire process of support disturbance from initial drilling to stabilization, the dynamic response data of the surrounding rock is extracted to provide a basis for real-time adjustment of support design during mechanical excavation.

[0042] Exemplarily, sensors (such as stress gauges, vibration monitors, and displacement meters) are arranged at the support points to quantify the independent disturbance energy of a single support point and its impact on the surrounding rock. The data that can be determined may include stress change, disturbance energy release, and crack extension range. A dynamic data acquisition system can be used to record stress changes and displacement changes per second as time series data. Multiple support points are set in key areas (such as high stress concentration areas), and drilling operations are performed according to the simulation parameters (synchronous disturbance rhythm) of mechanical excavation to simulate the cumulative effect of multi-point disturbances of mechanical excavation. Superimposed stress redistribution, crack network expansion, and vibration energy level changes. High-frequency dynamic monitoring equipment can be used to capture the nonlinear response of associated disturbances. The monitoring data is input into a numerical simulation model (such as the finite element method) to calculate the comprehensive impact range of support disturbances on the surrounding rock and predict high-risk areas in mechanical excavation. Disturbance energy distribution diagrams, crack extension patterns, stress concentration areas, and other information are obtained. Model correction can be combined with field data to improve prediction accuracy. Based on the similarity analysis between support disturbance and mechanical excavation disturbance, the initial support scheme is optimized. For example, the density of support points is increased in high-stress areas, the support stiffness of key parts is enhanced (such as using steel mesh), and the support depth and shotcrete thickness are dynamically adjusted. The surrounding rock response is monitored in real time during actual excavation to verify the optimization effect. Therefore, the support setting disturbance data provides the surrounding rock response characteristics under actual geological conditions, replacing the assumed errors of the idealized model. High-risk areas of mechanical excavation (such as stress concentration areas and crack expansion areas) are identified in advance, and the support design is dynamically optimized to reduce the incidence of accidents such as rock bursts and landslides. Accurate support design avoids excessive support and waste of support materials.

[0043] In summary, the deep underground cavern support evaluation method based on disturbance energy provided in the above embodiment determines the initial support point distribution information of the initial support scheme based on the initial ground stress field to evaluate the independent influence characteristics of each initial support point on the surrounding rock when supporting drilling and the associated influence characteristics of multiple initial support points on the surrounding rock when supporting drilling is performed simultaneously; based on the independent influence characteristics and the associated influence characteristics, a support drilling simulation scheme similar to the mechanical excavation disturbance is determined, and the support drilling simulation scheme includes the drilling position distribution and the drilling depth; the actual disturbance information during the execution of the support drilling simulation scheme is monitored to optimize the initial support scheme based on the actual disturbance information. Therefore, in traditional underground cavern construction, support setting is usually regarded as a separate protection process, and the disturbance generated is regarded as an inevitable construction impact. However, this scheme regards the disturbance generated during the support setting (especially drilling and anchor installation) as a valuable experimental condition to simulate the disturbance characteristics of subsequent mechanical excavation, thereby providing real and accurate reference information. The inevitable disturbances in the support setting process are converted into valuable surrounding rock response experiments, thus avoiding the need for additional simulation experiments and saving resources and time. By monitoring the propagation of disturbance energy and stress redistribution during the support process, the surrounding rock response data under real geological conditions are extracted as an important basis for subsequent mechanical excavation design.

[0044] In one embodiment, it also includes:

[0045] The disturbance data during the drilling and bolt setting process are monitored to obtain the independent impact characteristics.

[0046] In one embodiment, it also includes:

[0047] The disturbance data during the drilling and bolt setting process of different initial support points are monitored to obtain the associated impact characteristics.

[0048] It can be understood that by monitoring the disturbance data during the drilling and anchor setting process, the independent influence characteristics of each support point are extracted, and the disturbance data during the coordinated construction of multiple support points are monitored at the same time to obtain the associated influence characteristics. The independent influence characteristics can be the local disturbance response of the surrounding rock during a single drilling or anchor setting process, including the independent characteristics of stress release, deformation and vibration. It reflects the local disturbance effect of each support point on the surrounding rock. The associated influence characteristics can be the comprehensive response of the surrounding rock when multiple support points are drilled or anchored at the same time, including the superposition of disturbance energy, stress field interaction and crack propagation mode. It can simulate the complex effects of multi-point disturbance during mechanical excavation.

[0049] Exemplarily, for the monitoring and evaluation of independent influencing features, surrounding rock monitoring sensors can be arranged at a single initial support point to monitor the disturbance data during drilling or anchor setting. Monitoring parameters may include: stress changes (stress release curves around the support point are recorded by stress sensors); displacement and deformation (the deformation of the surrounding rock is monitored by displacement sensors); vibration characteristics (frequency and amplitude are recorded by vibration sensors). The monitoring data is analyzed to extract the following features: maximum stress release, the amplitude of the surrounding rock stress change after drilling or anchor setting; disturbance range, the influence radius of surrounding rock stress or deformation; disturbance energy, based on the vibration frequency and amplitude, the energy release of a single point disturbance is estimated. For the monitoring and evaluation of associated influencing features, drilling or anchor setting can be performed simultaneously at multiple initial support points to monitor the comprehensive disturbance response of the surrounding rock. Multiple stress, displacement and vibration sensors are arranged around the excavation area to cover the range of a single support point and its overlapping area. Monitoring parameters may include: comprehensive stress release (superimposed stress changes when multiple points act in concert); associated disturbance range (influence radius of surrounding rock under the joint action of multiple points); superimposed vibration mode (changes in vibration spectrum when multiple points act simultaneously). Regarding the extraction of associated disturbance features, it may include: stress field superposition, analyzing the interaction of stress fields caused by multiple support points, identifying superimposed stress concentration areas; crack extension characteristics, monitoring the extension direction and mode of cracks, identifying potential damage paths; disturbance energy accumulation, calculating the cumulative energy release based on multi-point vibration data. For example, the associated disturbance feature shows that the stress field superposition area caused by the top support point is stress concentrated, and the crack extension preferentially develops toward the top. By comparing the single-point independent feature with the multi-point associated feature, the difference between the local effect and the overall effect can be identified. For example, the influence radius is 1.5 meters when a single point acts, while it extends to 3 meters when multiple points act. The trend of stress field changes can be identified. Independent disturbances are mainly concentrated near the support points, while associated disturbances show obvious stress field superposition effects. According to the comprehensive evaluation of independent and associated features, the position, spacing and depth of the support points are adjusted. Add support points in the associated disturbance stress concentration area. Enhanced support (such as denser anchors, steel supports, etc.) is used for the expansion area of ​​associated disturbance cracks. The optimal spacing and distribution of single-point action are determined based on the independent influence characteristics. The density of support points in high-risk areas is optimized based on the associated influence characteristics. The support strength is increased in areas where stress concentration is caused by associated disturbances, and higher-strength anchors or steel supports are used. During the construction process, the support design is dynamically adjusted in combination with real-time monitoring data. New cracks or stress concentration areas are discovered based on real-time data, and temporary support is added. Therefore, by monitoring the independent and associated disturbance characteristics generated during the support process, the true stress changes and crack expansion laws of the surrounding rock are obtained, providing an accurate reference for subsequent mechanical excavation. The support design based on disturbance characteristics is more in line with actual geological conditions and significantly reduces the risks of rock bursts and landslides. By accurately arranging support points and dynamically adjusting support strength, material waste caused by excessive support is reduced.

[0050] In one embodiment, it also includes:

[0051] The independent impact characteristics are obtained based on the disturbance data during the drilling and anchor setting process of different initial support points, and the associated impact characteristics are obtained by predicting the disturbance data during the drilling and anchor setting process of different initial support points in combination with the ground stress field model.

[0052] For example, the geostress field model provides the initial stress distribution of the surrounding rock, which is an important basis for simulating and predicting the disturbance response of the support point. It reflects the stress equilibrium state of the surrounding rock in the undisturbed state. By combining the geostress field model with the monitoring data, the disturbance energy superposition effect and correlation characteristics when multiple support points are operating simultaneously can be predicted more accurately. Through actual monitoring data, the disturbance effect of a single support point is quantified, and the independent influence characteristics are used as the direct impact assessment of the local area. Combined with the geostress field model, the synergy of different support points is predicted and simulated, and the correlation influence characteristics can evaluate the mutual influence of disturbances between support points. Through the joint analysis of disturbance data and geostress field model, the layout of support points and the construction sequence are optimized to improve the safety and efficiency of support design. For example, the disturbance sources of multiple support points are added to the geostress field model to simulate the stress field changes when different support points are operating simultaneously. The finite element method (FEM) can be used to analyze the stress superposition and crack extension of multiple support points. Combined with dynamic simulation, the superposition effect and propagation range of vibration energy are calculated.

[0053] According to some embodiments, further comprising:

[0054] Obtain the initial stress field distribution of rock mass based on the initial geostress field;

[0055] Identify the possible high stress concentration areas during mechanical excavation, and the support boreholes in the support drilling simulation scheme are distributed in the high stress concentration areas to truly reflect the disturbance effect of mechanical excavation. For example, support boreholes need to be arranged in key parts (top, side wall and bottom) of the future excavation contour. Dense boreholes are arranged in high stress concentration areas, and sparse boreholes are arranged in low stress areas. The spacing setting refers to the action radius of the mechanical excavation cutter head and the mechanical properties of the surrounding rock.
