Development and Application of Anchor Dynamometer in Similar Simulation Experiment
摘要
Abstract
To make better real-time observation on the anchor's stress in different positions of roadway, the roadway similar material model can be used to analyze the deformation and failure mechanism of surrounding rock, and provide scientific basis to determine reasonable support parameters of roadway. In this paper, a new type of stress sensor was designed by using LY-12 duralumin alloy as elastic mate-rial. By contrast analysis of disadvantages of present anchor dynamometers, the sizes of whole-bridge ring anchor dynamometer in no-hole status was determined by using material mechanics theory. In addi-tion, the stress distributions of anchor dynamometer in the statuses of no-hole and with a hole were con-trast analyzed through the numerical calculation model built by FLAC3D. The experiment calibration and application results show that the structure size, stability and accuracy, et al of the new dynamometer are all appropriate for the requirements of similar material simulation experiment, which can provide an impactful means for testing anchor stress in similar material simulation experiment, and has wide pros-pect of application.关键词
