为研究路堤荷载作用下斜坡软弱土地基的变形特性，考察打入桩和抗滑桩加固斜坡软弱土地基的效果.结合典型工点土的物性指标，进行了三组1 :10斜坡软弱土地基路堤的离心模型试验(无加固措施、打入桩加固、抗滑桩加固)。试验数据表明.地基变形主要发生在路堤下侧边坡下;打入桩和抗滑桩能约束斜坡软弱土地基的变形，提高其稳定性;打入桩方案约束变形的效果优于抗滑桩方案。

To study the deformation characteristics of slope soft-soil foundation under the loads of embankment，and investigate the reinforcement effects of driven piles and stabilizing piles，three groups of centrifugal model tests，separately with no reinforcement measures，driven piles and stabilizing piles，are carried out based on physic-mechanics parameters of a typical slope soft-soil foundation. The results obtained show that the deformation of foundation is mainly concentrated on the border side of the declivity, and that both driven piles and stabilizing piles can limit deformation of the slope soft-soil foundation and increase the stability of foundation, and that the effects of driven piles applied in control of deformation turn out to be more conspicuous than that of stabilizing piles.
