Abstract

The invention provides a device and a method used or monitoring rock strata movement in three-dimensional similar material simulation experiment. According to the method, a steel tube is arranged at a point to be measured so as to form a vertical detection channel, and the outer wall of the steel tube is provided with scales so as to realize positioning of the point to be detected; after positioning, claw-type probes are delivered into the steel tube, and are pushed to designated spots with a push rod; the probes are arranged at the right spots via the method above from bottom to top; the steel tube is removed; measuring lines are stretched to be straight, and are connected with a linear displacement sensor via pulleys; and a computer is used for controlling the linear displacement sensor so as to realize real-time observation and storage of data. The device and the method can be used for observing rock strata movement amount in models accurately, and realizing real-time collection and storage of data, is simple in structure, low in labor intensity, and excellent in observation effect.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to a device and method for monitoring rock formation movement in a three-dimensional similar material simulation experiment. Background technique [0002] In the three-dimensional similar material simulation experiment, it is very important to monitor the movement of the rock formation inside the model. After the model is excavated, the rock formation will collapse downward due to the influence of gravity and the excavation process. Therefore, during the collapse process, the subsidence of each rock layer is generally different. By observing these deformations, we can know the displacement of the rock layers inside the model. [0003] In the study of overlying rock movement laws, two-dimensional plane models are generally used, strain gauges are arranged in the model or observation points are set on the surface of the model, and then the movement of rock strata is obser...
