How the change of space between driven piles and stabilizing piles and how the change of exertion coefficient of the between - pile soil intensity parameters will influence the foundation stability are analyzed . the safe space between piles of different reinforcement schemes is initially confirmed . the test results and stability analysis indicates that : it is safer to construct embankment upon level soft - soil foundation than slope soft - soil foundation ( 1 : 10 ) ( 2 )用土工专业软件geo - slope对不同情况下的地基进行了稳定性分析，结合斜坡软弱土地基路堤的离心模型试验结果与室内土工试验测得的参数，推求出了地基土的强度指标；分析了软弱土层c 、值的变化对地基稳定性的影响；探讨了打入桩方案和抗滑桩方案桩间距的变化和桩间土强度参数的发挥系数的变化对地基稳定性的影响，初步确定了不同加固方案的安全桩间距。
