Abstract

The invention discloses a 3D (Three-Dimensional) similar physical testing device for simulating fault dislocation. A testing stand is provided with a scale identifying structure; a testing model blockcomprises a transparent acrylic plate rectangular box body and testing soil; the transparent acrylic plate rectangular box body is filled with the testing soil; the transparent acrylic plate rectangular box body is arranged in the testing stand and is tightly fitted with the testing stand; first loading plates are horizontally arranged on the bottom end surface of the transparent acrylic plate rectangular box body; second loading plates are vertical to the first loading plates and are located on the end surface of one side of the transparent acrylic plate rectangular box body. According to the 3D (Three-Dimensional) similar physical testing device for simulating the fault dislocation, provided by the invention, the fault occurrence can be accurately simulated, meanwhile, a fault activation process can be quantitatively simulated on the premise that '3D box effect' is prevented from happening and a simulation initial stress field is ensured, observation on a lining cracking process anda failure mode can be realized, the testing accuracy and the testing reasonability are ensured, and the testing normalization and the testing operability are increased.

Description

technical field

[0001] The invention relates to the technical field of test devices, in particular to a three-dimensional similar physical test device for simulating fault dislocation. Background technique

[0002] Similarity simulation test has always been the mainstream test verification method in today's test research. Similar materials are used to simulate real engineering conditions such as tunnels and underground structures, and experiments are used to observe and study mechanical phenomena such as deformation, movement and destruction of engineering lining structures and surrounding rock masses. , through similar simulation tests to further understand the mechanism of lining-surrounding rock coupling stress transformation, which is very beneficial for seeking effective tunnel engineering lining-surrounding rock coupling ultimate stress threshold.

[0003] A large number of engineering practices have shown that tunnels and underground engineering fault sections are the...
