Abstract

A method for measuring deformation of a rock area is provided. The method comprises the following steps: (1) forming thin film paper; (2) making the plastic thin film face cling to the surface of a rock sample to be measured and integrating the rock sample to be measured with the plastic thin film face; (3) placing a camera on the upper layer of an iron support, fixing the rock sample to be measured to the lower layer of the iron support, and shooting a distribution situation graph of grids or points on the paper before the deformation of rocks; (4) exerting force on the rock sample and generating deformation, and using the camera to shoot a distribution situation graph of the grids or the points on the paper after the deformation of the rocks; (5) using graphic processing software to processing the distribution situation graphs of the grids or the points on the paper before the deformation of the rocks and after the deformation of the rocks, and completing measurement of the deformation of the rock area by measuring the position change of the grids or the points. By means of the method for measuring the deformation of the rock area, the problems that expensive instruments are needed, the technical requirement is high, and the operation is complex can be solved. The operation method is easy to implement, high in precision, economical and wide in application range. In addition, the experiment devices are simple.

Description

technical field [0001] The invention relates to a method for measuring rock deformation, especially a method for measuring rock area deformation. Background technique [0002] The identification and measurement of rock deformation are becoming more and more important for scientific research and practical applications, so many measurement methods have been produced. There are two main existing methods: [0003] 1. Real-time digital holography measurement [0004] This method applies the basic principle of laser real-time digital holographic interferometry, designs and builds an experimental measurement system for real-time digital holographic measurement of the lateral compression deformation process of the plexiglass plate, and continuously and dynamically captures the real-time digital holography of the plexiglass plate during the lateral compression process. The video file of the interference fringe pattern is processed by MATLAB programming to obtain the video file of th...
