Description

technical field

[0001] The invention belongs to the technical field of rock mechanics tests, in particular to an experimental device for simulating the two-dimensional rock-breaking process of a tunnel boring machine (TBM), through which the rock-breaking mechanism of the tunnel boring machine can be studied, and it is the construction equipment and construction parameters for long tunnels. In addition, this device can also provide a new experimental method for the study of rock mass fracture. Background technique

[0002] TBM is the English abbreviation of tunnel boring machine, which is a kind of tunnel boring machine specially for hard rock. The excavation process of the tunnel boring machine includes: the hob penetrates into the rock mass on the tunnel face through thrust, and the rotation of the cutterhead drives the hob on the cutterhead to crush the rock mass, so that the rock on the tunnel face is broken into fragments. Therefore, the tunnel boring machine has uniqu...
