近几年来,在技术文献中出现了与传统的科学技术观点不同的关于巷道围岩破坏的新见解。在维修巷道时通过测站的测点观测证实,巷道围岩的移动具有环状特征,在岩体内出现离巷道周边很远的裂开的裂隙。为了验证这一事实和确定环状破坏发生的条件,全苏矿山地质力学和测量科学研究所用相似材料模拟实验进行了巷道围岩破坏特性的研究。利用平面模型和立体模型在连 In recent years, new ideas on the destruction of roadway surrounding rocks have emerged in technical literature that differ from traditional scientific and technical points of view. During the maintenance of roadway, it is confirmed by the observation of measuring points at the station that the surrounding rock of the roadway has a ring-like feature and cracks are formed in the rock mass far away from the perimeter of the roadway. In order to verify this fact and determine the conditions of annular failure, the research on the failure characteristics of surrounding rock in tunnels was carried out by simulating experiments with similar materials in the Institute of Geomechanics and Surveying Science. Use the plane model and the three-dimensional model in the even
