Description

Technical Field

[0001] The invention relates to the technical field of ground stress testing, and in particular to a ground stress testing system for a track tunnel. Background Art

[0002] The track tunnel is a large tunnel used for laying tracks in underground mines, coal mines and other underground projects to transport materials such as ore and coal, as well as the passage of personnel and equipment. It is an important part of the underground transportation system. Its size is usually large and can meet the operating requirements of locomotive-drawn mine cars and other transportation equipment. The normal operation of the track tunnel is crucial to the production efficiency and safety of the entire underground project. The test of the ground stress in the track tunnel is of great significance to ensure the safety and stability of the tunnel, optimize the construction plan, prevent geological disasters and improve production efficiency. Therefore, in mines and underground projects, the ground stress test should be highly valued to ensure the accuracy and reliability of the test results.

[0003] At present, before conducting ground stress testing on rail tunnels, it is necessary to drill holes in the tunnels and install sensors. However, when the drill bit encounters hard points in the rock or changes in geological structure during the drilling process, sudden high-intensity, high-frequency vibrations and impacts will occur. These vibrations and impacts will propagate in the rock in the form of waves, causing serious disturbances to the rock. Therefore, operators are required to judge and change the drilling strategy based on the status of the drilling when drilling, which is greatly affected by human factors and has low efficiency.

The corresponding activity intensity is obtained according to the activity information. When the activity intensity is greater than the preset threshold, the corresponding activity information is marked as a high-risk activity, and the ratio of the number of high-risk activities to the length of the corresponding test time period is calculated to obtain the high-risk activity probability value; The rock mechanical properties include elastic modulus and Poisson's ratio, and the stress values ​​in the x, y, and z directions are obtained. The generalized Hooke's law is used and the formula Calculate the rock strain value ε in the corresponding direction x ; where ε x is the strain value in the x direction, E is the elastic modulus, υ is the Poisson's ratio, σ x , σ y , σ z They are expressed as stress values ​​in the x, y, and z directions respectively; the strain values ​​in each direction are calculated respectively, and when the strain value is greater than the preset strain threshold, the part of the strain value greater than the strain threshold is marked as the strain influence value, and the strain influence values ​​corresponding to each direction are calculated and summed to obtain the total strain influence value; A rectangle is constructed with the values ​​of the uneven impact value and the high-risk activity probability value as the long side and the wide side of the rectangle, and then a straight line perpendicular to the rectangle is drawn with the center of gravity of the rectangle as the starting point. The length of the straight line is equal to the value of the total strain shadow value, and then a quadrangular pyramid is constructed with the rectangle and the straight line. The volume of the quadrangular pyramid is calculated and the value of the volume is marked as the ground stress state value. When the ground stress state value is greater than the preset threshold, the corresponding ground stress state information is generated as ground stress state anomaly.
