摘　　要：在研究岩土工程的整体稳定可靠度分析及二维随机界面元法的基础上,建立了等参随机界面元法的数学模型,推导了基本公式,编制了计算程序,以均质边坡的抗滑可靠度分析作为数值算例,并就计算结果进行了分析和探讨.Based on overall stablility reliability analysis by Stochastic Interface-Stress Element Method(SISEM) for 2-D problems, the mathematical model for 3-D iso-parametric SISEM is constructed. Basic formulas are deduced and computer program is developed. In analysis of anti-slide probability of homogeneous slope, the reasonable conclusion is drawn.Since inter-stress element method (ISEM) is well applied to solve many problems, such as nonlinear, dynamic, viscous, stable and field problems, 3-D SISEM may be applied to wider area due to describing structural stability more detailed than traditional method. But many works still should be carried out before that. In addition, the problem involved in discontinuous medium can be also solved by SISEM.
