| 摘 要： | 为了研究高地应力作用下巷道围岩的蠕变规律,利用ANSYS强大的非线性蠕变计算功能,对深部围岩巷道进行模拟,建立几何模型以及蠕变模型,并利用实验测得的岩石力学参数,通过ANSYS软件计算,一方面验证非线性流变理论,另一方面找出深部蠕变的一些规律,与试验结果进行比较分析。结果表明:用ANSYS进行土力学、基础工程学和岩体力学领域的计算、分析,精度非常高,对于实际深部开采有一定的指导意义。

| Abstract: | The ANSYS software,which is powerful in non-linear creep calculation,is used to study the rules of laneway wall rock creep at the high geostatic stress.The deep laneway wall rock is simulated and geometric model and creep model are built.Besides the rock mechanics parameters are obtained by the experiment.Through the calculation of ANSYS software,one is that the theory of non linear creep is confirmed,the other is that the rules of non-linear depth creep theory are discovered and the test results are compared.The results show that the analysis with ANSYS is so extremely high on the fields of soil mechanics,the foundation engineering and the rock mechanics,which has certain guiding significance in depth mining. |
