Abstract

The invention belongs to the technical field of rock mass engineering geomechanics, aims to solve the problem of poor reliability of data obtained by an existing test device, and particularly relatesto an experimental system and method for simulating the influence of fracture stick-slip dislocation on tunnel engineering, which comprises a model box system and a stick-slip loading system, and themodel box system is used for simulating the interaction between two fault panels; the stick-slip loading system comprises a first loading assembly, a second loading assembly and a bearing assembly; the first loading assembly comprises a first loading device and a first sample frame for placing a main loading rock mass sample; the supporting assembly is arranged at the side part of the first sampleframe; the sub-loading rock mass sample supported by the supporting assembly can be propped against the main loading rock mass sample under the action of the second loading assembly; and according tothe invention, reliable and effective simulation test data can be obtained.

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...
