| description | The invention discloses a device and a method for a physical simulation test of the stability of a deep tunnel surrounding rock and relates to a rock-soil mechanic technology. A structure of the device is that a pressure plate is covered on a sample in a deep tunnel rock body model instrument, and a vertical pressure system is arranged on the pressure plate and used for loading so as to simulate and exert gravity stress. A miniature shield machine drills into the sample from a drilling surface, and the miniature shield machine, a stepless speed changing box and a motor are sequentially connected to achieve drilling. Eight optical fibers and six strain gauges are distributed in the sample, the optical fibers are connected with a distributed optical fiber monitoring system, and the distributed optical fiber monitoring system and the strain gauges are respectively connected with a data acquiring system so as to achieve detection and recording. By means of the device and the method for the physical simulation tes |
