软岩流变模型实验相似准则的推演及应用
Deduction and application of similarity criteria in soft rock rheological model experiment
摘要
Abstract
In order to overcome the problems of long delay and low efficiency of indoor testing on rock properties and provide a timely and accurate scientific guidance to safe rock support on site, the similarity criteria that must be satisfied by the model and prototype in soft rock model test are derived using the dimensional analysis of similarity theory. Also, the similarity relations that must be satisfied by the physical quantities of model and prototype in soft rock model test are obtained. Based on the similarity criterion and the similarity relations, a suitable material not only can simulate the rheological mechanical properties of soft rock, but also can obtain a higher time-ratio between prototype test and model test. This study provides an important theoretical basis for developing new test method which can simply, rapidly and efficiently test soft rock rheological properties.关键词
