Description
technical field [0001] The invention belongs to the technical field of rock mass engineering geomechanics experiments, and in particular relates to an experimental system and method for simulating the influence of fracture stick-slip dislocation on tunnel engineering. Background technique [0002] In the construction of major projects in active tectonic areas, the stability of tunnels crossing active faults is generally faced. Therefore, it is urgent to study the influence of active fault dislocation on tunnel engineering. The existing research is mainly carried out through the physical simulation of the model box, and the realization of the loading method is mainly based on the stable dislocation, and there is a lack of loading devices and methods for the fracture stick-slip dislocation. The test device for simulating near-fault earthquakes caused by reverse fault stick-slip dislocation disclosed in existing patents uses a pressure-sensitive micro-explosion device to simul...
