[0002] The most important thing to ensure the stability of the rock mass in engineering is to ensure the stability of the filling joint, and the filling joint, especially the filling joint containing the soft interlayer, is most prone to shear failure. The existence of the soft interlayer in the filling joint in actual engineering often leads to frequent accidents, causing serious loss of life and property. Therefore, it is particularly important to remove the soft interlayer in the filling joint to make the overall rock mass more stable.
