软土地区不同深基坑支护结构形式的分析比较

Analysis of Different Support Structures in Soft Deep Foundation Pit

通过对软土地区4个不同类型深基坑支护工程的监测成果进行分析比较,揭示不同支护结构形式的变形规律。基坑支护结构的形式应根据基坑开挖深度、土质情况、周边环境等特点进行合理选择,既确保基坑与周边环境的安全,又做到经济可行。

By analyzing monitoring results of support of four different deep soft foundation pits, deformation law of different support is found. The support should be determined by excavation depth of foundation pit, soil conditions, surrounding environments. The support should ensure the safety of surrounding environments is economic.
