摘要
本文根据地下水对岩石边坡稳定性的影响与岩体的孔隙率及地下水的密度有关的观点,导出了渗流场情况下的线弹性静力学平衡方程.在边界积分方程中,用伽辽金张量把体积力面积分转化为边界上的线积分.将边坡中的临界滑动面作为边界,用边界元法求出了其上的面力,并由此计算其安全系数.
According to the point of view that the influence of groundwater on rock slopes stability is related to the porosity of rockmasses and the density groundwater, this paper has derived linear elasto-static equilibrium equations considering seepage field. In the boundary integral equation, the surface integral of the body force was transformed into a line integral in the boundary by use of Galerkin vector. Regarding the critical sliding surface in slope as a boundary, tractions acting on it were calculated by the boundary element method and thereby the safety factor was obtained.
