FEM for Coupling of Solid and Liquid Phases and Its Application

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 FEM for coupling of solid and liquid phases in the rock was investigated with consideration of the coupling effict of pore pressure of ground water and deformation of the rock. A calculation model for the head of pore water has been established and the distribution of stresses of certain land slope under the action of gravity field and the head of pore water was analyzed and calculated. The results show htat the FEM for coupling of solid and liquid phases can reflect the influence of ground water on the distribution of stresses and displacement and deformation of the rock.
