| 摘 要： | 介绍真空-堆载联合预压加固软基的特点,根据不同的荷载比例进行室内模拟试验,从应力路径、强度、沉降量、排水量等方面来分析。试验结果表明:真空荷载的比例越大,排水量越大,土体收缩量越大,土体越安全;堆载的比例越大,则沉降量相对会大一些,应力路径更易向破坏线靠近,增加不稳定因素。

| Abstract: | The technology of vacuum-loading compaction for soft soil is described.Lab simulation experiment is conducted according to different load ratio through analyzing the stress path,strength,settlement and displacement,etc.The experiment result indicates that larger vacuum load leads to a greater displacement,more soil shrinkage,and safer soil ground;And a larger load ratio leads to a greater settlement,and the stress path tends more likely to the failure line. |

| Keywords: | vacuum-loading compaction simulation experiment stress pass displacement |
