| 摘 要： | 以扬州市某条市政道路为例,介绍真空预压法加固软土地基沉降计算过程及各计算参数的取值情况;通过对软土区施工过程的沉降观测资料及工后对软土区的室内物理力学性质指标分析来看,采用真空预压法是可行的;其真空度的取值、固结度的选用是合理的,由此计算方法所得到的真空预压时间是正确的,其工后沉降满足规范要求。

| Abstract: | In this paper,the caculation processes of vacuum preloading method for strengthening soft foundation is introduced through analysis of certain urban road in YangZhou.This method is proved feasible through analyzing the observed sedimentation data of soft foundation area and indoor physical character criterion of soft foundation area.The selection of vacuum value and concretion degree is reasonable.Therefore the vacuum preloading time caculating is accurate.The sedimentation after construction complies with the criterion. |
