摘要

讨论了抗滑桩加固边坡的稳定分析研究状况，在全面地考虑基质吸力和抗滑桩对边坡稳定性的贡献后，利用所发展的可考虑基质吸力的弹塑性强度折减有限元程序，探讨了抗滑桩加固前后的非饱和土边坡整体稳定性，并且与相应不考虑基质吸力条件下的边坡稳定性进行了对比分析。

Abstract

The contribution of matric suction and stabilizing piles to the global stability of unsaturated soil slope should be properly evaluated in practice. Methods of design and analysis for slope reinforced with piles are firstly discussed and reviewed. Then

by making use of the strength reduction finite element codes

the global stability of unsaturated soil slope are analyzed. Four cases are combined according to the conditions of stabilizing piles and matric suction. The comparison of results can evaluate quantitatively the effect of matric suction on slope.
