本文探讨了岩体内固液相耦合的有限元分析方法，考虑了地下水孔隙压力与岩体变形之间的相互耦合作用。建立孔隙水压的计算模型．并计算分析了在重力场和孔隙水压力共同作用下某露天边坡的应力分布特点。结呆在明，固液相耦合的有限元法能反映地下水对岩体工程的应力分布和位移变形的影响。
In this paper, the finite element analysis of solid-liquid coupling in rock mass is discussed, and the mutual coupling between pore water pressure and deformation of rock mass is considered. The establishment of pore water pressure calculation model. The stress distribution characteristics of an open slope under the combined action of gravitational field and pore water pressure are calculated and analyzed. The results show that the finite element method coupled with solid-liquid coupling can reflect the influence of groundwater on the stress distribution and displacement of rock mass engineering.
