碎裂岩体加固的正交有限元分析

Analysis on Reinforcement of Cataclastic Rock Mass with Orthogonal Finite Element Method

利用ANSYS建立碎裂岩体加固的数值计算模型,对影响巷道围岩位移的诸多因素进行正交分析,分别得到各单个影响因素对巷道围岩位移量的影响规律,以及各因素的多元线性回归方程,并且对诸个因素的影响程度进行了排序。

In this paper, a numerical computing model for the reinforcement of cataclastic rock mass is established by the use of ANSYS program. The orthogonal analysis on the influencing factors of the displacement of surrounding of roadway is carried out. The influent rules of every factor on the displacement of surrounding of roadway are drawn out. A group of multivariate linear regression equations for the influencing factors are obtained. And the influencing factors are sorted by their influencing degrees.
