在考虑非饱和基质吸力条件下，基于Bishop单值有效应力非饱和土强度理论和Fredlund双应力变量非饱和土强度理论，探讨在传统的Sarma法中实现非饱和边坡的稳定性分析的思路和方法，开发了可考虑基质吸力的Sarma条分法的相关程序，并针对一个非饱和土滑坡进行稳定性分析，结果表明：两种改进的Sarma法在分析非饱和土边坡时基质吸力影响的考虑方式不同，这种差异会对计算结果产生一定影响，但误差是有限的。

With an aim at the study on the Sarma's slice method of unsaturated slope stability, the different treatments of matric suction in the Sarma's slice method are analyzed based on the Bishop's unsaturated strength theory and Fredlund's unsaturated strength theory respectively; then, the corresponding program codes of the Sarma's slice method which can consider matric suction differently are developed individually; and then, the application of these two developed methods on the stability analyses of an unsaturated soil slope are also discussed. Finally, the computational results show that there are some differents in considering the impacts of the matrix suction on anysis of the unsaturated soil slope using these two improved Sarma methods, but the error is limited.
