| 摘 要： | 在岩石工程实践的数值模拟过程中,工程岩体特性参数决定着模拟结果的好坏。根据NMohammand等人得到的实验室测试数据与原位测试的拟合结果,确定了数值模拟中各层岩体的杨氏模量与泊松比,同时,根据Drucker-Prager系列修正屈服准则间的关系,使用适于平面应变条件的D-P屈服准则,确定了数值模拟中各层岩体的粘聚力及内摩擦角。在此基础上,使用大型有限元程序Ansys,以东海煤矿深部开采巷道为例,对深部开采巷道顶底板的稳定性进行数值模拟,在取得巷道变形实测数据后,经比较,所得出的模拟结果与实际相符。

| Abstract: | Rock mass characteristic parameters of engineering determine the quality of numerical simulation results in numerical simulation of rock engineering practice.Based on the test data acquired by N Mohammand et al in the laboratory and fitting results in situ test,the Young modulus and Poisson ratio of each rock body in the numerical simulation are determined.Meanwhile according to the relationship between Drucker-Prager modification yield criterion,the cohesion force and internal friction angle of each rock b... |
