运用FLAC3D岩土软件对某地铁一号线深基坑进行开挖与支护的模拟,计算中采用摩尔-库伦弹塑性模型.通过计算得出基坑水平位移、墙后土体水平位移、地表沉降,并与实测结果进行比较,可为深基坑工程施工与支护提供参考.
Using the software FLAC3D to simulate the excavation and support of the deep foundation pit of a Subway Line 1, the Mohr-Coulomb elasto-plastic model is adopted in the calculation, and the horizontal displacements of the foundation pit, horizontal displacements of the soil behind the wall, Settlement, and compared with the measured results, which can provide reference for the construction and support of deep foundation pit engineering.
