Abstract

The invention discloses a platform and a method for the indoor large-scale comprehensive simulation and test of the tunnel dangerous rock collapse. According to the invention, a single-block dangerousrock instability simulation system, a fractured rock mass multi-block instability simulation system, a complex tunnel environment quantitative simulation system and a data collecting and processing system are utilized to respectively simulate the progressive instability process of a single rock block along with the excavation of a tunnel heading surface, the instability process of the surroundingrock of the fractured rock mass under the influence of the tunnel excavation operation, and the real environment of the dim, dusty and moist condition of the tunnel. Meanwhile, the structural surfaceinformation on the surface of the rock mass in different tunnel simulation environments is collected. As a result, the stability of the fractured rock mass after being excavated can be monitored.

Description

technical field [0001] The invention relates to an indoor large-scale comprehensive simulation test platform and method for the collapse of dangerous rocks in tunnels. Background technique [0002] There are many disaster problems in the construction and operation of tunnels and other underground caverns. During the tunnel construction process, a large number of dangerous blocks are formed due to the intersecting combination of the structural planes of the surrounding rock of the tunnel. Under the action of construction disturbances, these dangerous blocks tend to lose stability and fall, resulting in casualties of construction personnel and damage to mechanical equipment. Therefore, the acquisition and analysis of rock mass structure information is an important means to avoid dangerous rock collapse disasters. [0003] Due to the dark, dusty and high humidity environment during the tunnel construction period, the existing digital collection equipment for ground rock mass i...
