摘要
本文探讨岩体应力一渗流问题耦合分析的数值模拟方法。作者根据实际工程岩体的特征——含有孔隙并为各种结构面所切割,对岩体中的岩块和裂隙分别进行处理,然后对岩体裂隙应力—渗流问题进行耦合分析,从而建立相应的有限元方程。此方程可用于实际工程岩体的稳定性分析。
An approach to the digital simulation of the coupled analysis of rock-stress/influent(vadose) problem is investigated. Based on the features of the actual engineering rock formation, its porosity and intersection by different planes of the rock texture,the authors established a finite element equation in which the rock masses and the rock crevices are treated separately and then,the problem of the stress in pores and in the crevices of the rock formation,along with the influent(vadose),i. e. the rock-stress/ influent coupling problem, is mathematically analyzed. The proposed equation also applies to the stability analysis of the rock mass.
