软土路基处理前后地基土性质探析

On analysis of performances of foundation soil before and after the soft soil foundation treatment

以上海某高速公路的地基处理工程为例,通过对场地内影响工程的浅部土层在分别采用真空—堆载联合预压、堆载预压两种不同地基处理方法前后,其物理性指标和力学性指标的变化进行比较,分析了预压法地基处理前后地基土性质的变化特点,得出了一些有意义的结论。

Taking the foundation treatment project along an expressway in Shanghai as the example, the paper compares its physical and dynamic indexes before and after the two foundation treatments, that is, the vacuum-mound preloading method and preloading, in the site which affect the shallow layer of the project, analyzes the change features of the foundation soil before and after the pre-pressure treatment, and achieves some meaningful conclusion.
