Description

Technical Field

[0001] This invention relates to the field of underground engineering technology, and in particular to a method and related equipment for monitoring the stress of surrounding rock in a full-section tunnel. Background Technology

[0002] Full-face tunnel excavation utilizes a mobile drilling rig, drilling the entire tunnel face in a single pass and then blasting it to form the shape. Simultaneously, anchor-sprayed support or a pre-arch and post-lining approach is employed. This reduces the number of operations required on the surrounding rock and avoids repeated disturbance. However, the excavation process disrupts the original equilibrium stress distribution, affecting the stress distribution of the surrounding rock and potentially creating construction risks. Therefore, the study of surrounding rock stress is of great significance for tunnel excavation.

[0003] Current methods for analyzing surrounding rock stress data in full-section tunnel excavation involve conducting geological surveys of the surrounding rock within a defined area, constructing a stress model based on the survey results, and then refining the model using data obtained after excavation to acquire the surrounding rock stress data for the excavated tunnel within that defined area. However, this method fails to reflect the rock mass interactions between different defined areas within the tunnel as a whole. Consequently, the refinement of the stress model within the defined area lacks universality, affecting the model's accuracy and practicality. Summary of the Invention

[0024] Optionally, determining the preset range of the tunnel surrounding rock based on the tunneling route information, the structural information, and the composition information includes:

[0025] If there are sloping sections in the tunneling route, obtain the slope information of the tunnel;

[0026] Based on the slope information, a preset slope threshold for the surrounding rock of the tunnel is determined;

[0027] The preset slope range of the tunnel surrounding rock is determined based on the preset slope threshold.

[0028] If there are curves in the tunneling route, obtain the curve angle information of the tunnel;

[0029] Based on the turning angle information, a preset turning threshold for the surrounding rock of the tunnel is determined;

[0030] The preset turning range of the tunnel surrounding rock is determined based on the preset turning threshold.

[0031] The preset range of the tunnel surrounding rock is determined based on at least one of the preset range of the ramp and the preset range of the turn.

[0032] Optionally, determining the preset range of the tunnel surrounding rock based on at least one of the tunneling route information, the structural information, and the composition information includes:

[0033] Based on the structural information, the degree of slippage of the surrounding rock of the tunnel is determined;

[0045] As can be seen from the above technical solutions, the present invention provides a method and related equipment for monitoring the surrounding rock stress of a full-section tunnel. The method includes: acquiring the composition information of the tunnel surrounding rock; acquiring the structural information of the tunnel surrounding rock; determining the current center of gravity position of the tunnel surrounding rock within a current preset range based on the composition information and the structural information; acquiring the current pressure change at the current center of gravity position; and determining the current stress information of the tunnel surrounding rock within the current preset range based on the current pressure change. Current methods for analyzing the surrounding rock stress data of full-section tunnel excavation involve geological exploration of the tunnel surrounding rock within a set range, constructing a stress model based on the exploration results, and correcting the model based on the data obtained after excavation to obtain the surrounding rock stress data of the excavated tunnel within the set range. However, the stress model constructed using the above method cannot reflect the rock mass interaction between different set ranges within the entire tunnel. For example, if the surface of the current rock mass slides, some of the slided rock mass may remain on the surface of the rock mass of an adjacent segment, causing changes in the surrounding rock stress of the adjacent segment and the current segment. This results in the lack of universality in correcting the stress model within the set range, thus affecting the accuracy and practicality of the model. This application embodiment obtains the composition and structural information of the tunnel surrounding rock, determines the current center of gravity position of the tunnel surrounding rock, obtains the current pressure change at the current center of gravity position, and determines the current stress information of the tunnel surrounding rock based on the current pressure change. By observing the pressure change at the center of gravity position, the structural changes of the surrounding rock can be determined. Based on the structural changes, the structural impact of rock mass changes within the current preset range on the structure of rock mass within adjacent preset ranges can be determined, thereby improving the practicality and accuracy of the stress monitoring method.

[0051] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims. In the several embodiments provided in this application, it should be understood that the disclosed apparatus and methods can also be implemented in other ways, and the apparatus embodiments described below are merely exemplary.

[0052] like Figure 1 As shown in the figure, this application provides a method for monitoring the stress of surrounding rock in a full-section tunnel. The execution subject of this method can be a server or controller, etc., and the method includes:

[0053] Step S110: Obtain the composition information of the surrounding rock of the tunnel.

[0054] For example, the aforementioned compositional information includes the type and distribution of the surrounding rock of the tunnel. This compositional information can be obtained through geological exploration using methods such as radar detection and seismic reflection.

[0055] Step S120: Obtain the structural information of the surrounding rock of the tunnel.

[0056] For example, the aforementioned structural information includes the surface condition information of the tunnel surrounding rock and the vertical distance from the tunnel surface to the rock mass. This structural information can be obtained using rock mass scanning equipment and image acquisition equipment.

[0057] Step S130: Based on the above composition information and structural information, determine the current center of gravity position of the tunnel surrounding rock within the current preset range.

[0058] For example, the aforementioned current preset range is determined based on monitoring requirements. The density distribution of the tunnel surrounding rock can be determined based on the aforementioned composition information, and the mass distribution of the tunnel surrounding rock can be determined based on the aforementioned structural information. The aforementioned current center of gravity position can be determined based on the aforementioned current preset range, density distribution, and mass distribution.

[0059] Step S140: Obtain the current pressure change at the current center of gravity position.

[0060] For example, a pressure sensor can be set at the current center of gravity position to obtain the current pressure change.

[0061] Step S150: Based on the current pressure change, determine the current stress information of the tunnel surrounding rock within the current preset range.

[0062] By acquiring the composition and structural information of the tunnel surrounding rock, the current center of gravity position of the tunnel surrounding rock is determined, and the current pressure change at the current center of gravity position is obtained. Based on the current pressure change, the current stress information of the tunnel surrounding rock is determined. Through the pressure change at the center of gravity position, the structural changes of the surrounding rock can be determined. Based on the structural changes, the impact of the rock mass structural changes within the current preset range on the structure of rock masses within adjacent preset ranges can be determined, improving the correlation and integrity between stress monitoring objects, and thus improving the practicality and accuracy of the stress monitoring method.

[0063] According to some embodiments, the current pressure change at the current center of gravity position includes the direction of the current pressure change at the current center of gravity position and the numerical value of the current pressure change at the current center of gravity position.

[0064] By combining directional information, it is possible to further predict the rock mass sliding that may occur within the current preset range, and thus predict the impact of changes in surrounding rock stress within the current preset range on the surrounding rock stress in other preset ranges. This improves the correlation and integrity among stress monitoring objects, thereby enhancing the practicality and accuracy of stress monitoring methods.

[0065] According to some embodiments, prior to the step of obtaining the composition information of the tunnel surrounding rock described above, the method further includes:

[0066] Obtain tunnel excavation route information;

[0067] Based on the aforementioned tunneling route information, structural information, and compositional information, the preset range of the surrounding rock of the tunnel is determined.

[0068] For example, in the absence of a monitoring target, a preset range can be determined at equal intervals for the excavated tunnels that need to be monitored based on the tunneling route; in the presence of a monitoring target, the preset range can be determined based on the monitoring target.

[0069] Based on information about the tunneling route, structure, and composition, the distribution of stability in the surrounding rock can be determined, thereby assessing the impact of tunneling operations on the stress in the surrounding rock. Densely setting up monitoring areas within areas of high impact improves the sensitivity and quality of stress monitoring, while dispersing monitoring areas within areas of low impact saves on monitoring costs.

[0070] According to some embodiments, determining the current stress information of the tunnel surrounding rock within the current preset range based on the current pressure changes includes:

[0071] Based on the aforementioned current preset range, the initial stress information of the tunnel surrounding rock within the aforementioned current preset range is obtained, wherein the initial stress information includes the initial stress direction and the initial stress value;

[0072] Based on the current pressure changes and the initial stress information, the current stress direction and current stress value of the surrounding rock of the tunnel are determined.

[0073] For example, the target stress monitoring position can be determined based on the current center of gravity position, and initial stress information can be obtained based on the target stress monitoring position. The current stress information can be obtained based on the initial stress information and the current pressure change.

[0074] By obtaining the current pressure change direction and the current pressure change value at the current center of gravity position, and combining this with the initial stress direction and value information, we can obtain the current stress direction and value information more accurately, making the data more practical.

[0075] According to some embodiments, the above-described method for monitoring the surrounding rock stress of a full-section tunnel further includes:

[0076] Under the condition that the pressure at the current center of gravity changes within the current preset range, the motion of the surrounding rock of the tunnel is obtained;

[0077] Based on the above movement situation, at least one first target preset range adjacent to the above current preset range is determined;

[0078] Obtain the position of the first centroid of the tunnel surrounding rock within the preset range of the first target;

[0079] Obtain the first pressure change at the first center of gravity position of the tunnel surrounding rock within the preset range of the first target;

[0080] Based on the aforementioned first pressure change, the first stress information of the tunnel surrounding rock within the aforementioned first target preset range is determined.

[0081] For example, an image acquisition device can acquire an image of the rock surface within the current preset range based on the direction of pressure change at the current center of gravity. An image matching algorithm can then be used to determine the motion based on the rock surface images before and after the pressure change. The direction and displacement of the rock mass can be determined based on this motion, and at least one first target preset range can be determined based on the displacement and the distribution information of the preset range to which each tunnel surrounding rock segment belongs.

[0082] When the surrounding rock of the tunnel changes, the rock mass may move to other preset ranges or it may only move within the current preset range. Therefore, determining the first target preset range based on the movement and monitoring the stress information of the surrounding rock of the tunnel within the first target preset range, while ignoring preset ranges that are not affected by stress changes in the current preset range, can improve monitoring quality and efficiency and save monitoring resources.

[0083] According to some embodiments, determining the preset range of the tunnel surrounding rock based on the tunneling route information, the structural information, and the composition information includes:

[0084] In cases where there are sloping sections in the aforementioned tunneling route, obtain the slope information of the aforementioned tunnel;

[0085] Based on the above slope information, the preset slope threshold of the surrounding rock of the tunnel is determined.

[0086] Based on the aforementioned preset threshold for the ramp, the preset range of the ramp for the surrounding rock of the tunnel is determined.

[0087] In cases where there are curves in the aforementioned tunneling route, obtain the curve angle information of the aforementioned tunnel;

[0088] Based on the above turning angle information, the preset turning threshold of the surrounding rock of the tunnel is determined;

[0089] Based on the aforementioned preset turning threshold, the preset turning range of the surrounding rock of the tunnel is determined;

[0090] The preset range of the tunnel surrounding rock is determined based on at least one of the preset range of the ramp and the preset range of the turn.

[0091] When there are curves or slopes on the tunnel excavation route, the rock mass of the surrounding rock is more active and the stress changes are more obvious. Therefore, determining the preset range based on the slope and turning angle can improve the practicality of the monitoring data, and thus improve the practicality of the stress monitoring method.

[0092] According to some embodiments, determining the preset range of the tunnel surrounding rock based on at least one of the above-mentioned tunneling route information, the above-mentioned structural information, and the above-mentioned composition information includes:

[0093] Based on the above structural information, the degree of rockfall of the surrounding rock of the tunnel is determined;

[0094] When the aforementioned degree of slippage exceeds a preset slippage threshold, the preset structural range of the tunnel surrounding rock is determined based on the aforementioned degree of slippage, wherein the aforementioned preset slippage threshold is the degree of slippage corresponding to the slippage of the tunnel surrounding rock.

[0095] Based on the above composition information, the stability of the surrounding rock of the tunnel is determined;

[0096] When the stability level is less than the preset stability threshold, the preset stability range of the tunnel surrounding rock is determined based on the stability level, wherein the preset stability threshold is the stability level corresponding to the rupture of the tunnel surrounding rock.

[0097] For example, the degree of slippage can be determined based on the structural information of the surrounding rock and the unevenness of the rock surface. For instance, the degree of slippage of the surrounding rock can decrease as the unevenness increases, and the pre-defined structural range can also decrease as the degree of slippage increases. Alternatively, the degree of slippage of the surrounding rock can be determined based on its composition. For example, if the composition of the surrounding rock is complex, the pre-defined range can be narrowed; if the geological composition of the surrounding rock is active, the pre-defined range can also be narrowed.

[0098] Based on the structural and compositional information of the tunnel surrounding rock, the distribution of its slippage and stability can be determined, thereby assessing the impact of tunneling operations on the stress in the surrounding rock. Densely setting up monitoring areas within high-impact zones improves the sensitivity and quality of stress monitoring, while dispersing monitoring areas within low-impact zones saves on monitoring costs.
