相似材料模型试验方法在我国岩层地表移动学科中的应用始于五十年代,但应用的规模和研究的深度都比较有限。中国矿业学院岩层移动试验室两年来制作相似材料平面模型20余台。本文在所做工作的基础上仅就相似材料模型试验用于岩层移动规律的可信性进行探讨。一、模型干燥收缩的位移规律由于试验环境很难满足恒温、恒湿的 The application of similar material model test method in the field of ground surface movement in our country began in the 1950s, but the scale of application and the depth of research are relatively limited. China Institute of Mining rock mobile laboratory two years to produce similar material plane model of more than 20 units. Based on the work done, this paper only discusses the credibility of similar material model tests for the rule of rock movement. First, the model dry shrinkage of the displacement due to the test environment is difficult to meet the temperature, humidity
