摘　　要：结合有限元法、极限平衡理论和常微分方程的数值解法等，提出用于土坡稳定的滑移线数值分析法．该方法考虑土的应力应变关系和土坡失稳的破坏形式，从分析土坡应力分布的变化入手，直接确定临界滑裂面的位置。The numerical method of slip lines to analyze the stability of slops is presented by combining finite elememt method, theory of limit equilibrium and numerical analysis method of ordinary differential equation. In NMSL, the stress-strain relationships of soils and the failure forms of instable slops are considered. Beginning at the analysis of variation of stress distribution of a slop, the location of critical slip surface is directly determined, and the globe safety factor is calculated.
