| 摘 要： | 通过FLAC对大面积堆载作用下的软土地基进行数值模拟,得到了控制场地安全环境的关键位置处某一点的位移,以位移发生急剧变化时刻对应的堆载高度作为评判软土地基稳定性的指标.根据工程实践,这一思路是可行的. |

| Abstract: | Through numerical analysis(FLAC) to a soft groundsill beared with large area's deposits,some spot's displacements of those key regions are can got which control the security of yard.The height of deposits corresponding can attain the sharp changed inflexion of displacement,then this height can use as guideline to judge the stability of soft groundsill.It is proved feasible by practice. |
