| 摘 要： | 简要介绍了真空-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、沉降量及排水量等方面作了分析。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,沉降量相对大,应力路径更易靠近破坏线,不稳定因素增加。

| Abstract: | The characteristic of vacuum-surcharge preloading reinforced soft foundation is introduced in this paper.Indoor simulation test is carried out according to different load rates to analyze stress path,strength,settlement and water discharge of reinforced soft foundation.The result shows that higher rate of vacuum load causes more water discharge,more soil shrinkage and higher stability of soil mass.The higher rate of surcharge causes larger settlement,and stress path is easier to close to failure line and th... |
