摘要
本文分析了现在广泛应用于复合地基稳定分析的Ｐｒｉｅｂｅ方法和Ａｂｏｓｈｉ方法，指出了它们的优点和固有缺陷，指出应用有限元方法计算土条底部应力进行极限平衡稳定分析，特别是高速公路复合地基稳定分析的优点．然后对复合地基参数指标取不同数值的情况进行了稳定性计算，分析了复合地基各种参数指标对其稳定性的影响．
The paper analyzed the widely used methods proposed by Priebe and Aboshi etc. for stability analysis of composite foundations and pointed out their merits and demerits.It also showed the necesity of appliance of the finite element method to the stability analysis of foundations,especially for the composite foundations of highways.Finally,the paper analyzed the effect of the composite foundation parameters on its stability.
