通过分析工程实例中软土基坑支护结构的变形情况,得到了基坑施工后围护桩体变形规律。研究结果认为：由于一级平台主要由软土组成,基坑开挖后土体与支护结构出现向基坑内的蠕变变形,土体的变形导致工法桩前土体的被动抗力降低,从而加剧工法桩的变形。因此,在软土深基坑支护工程中考虑蠕变效应就显得极为重要。

Through the analysis of engineering example for soft soil foundation pit deformation of retaining structure,the foundation pit retaining pile body deformation law was obtained.The result showed that because the first level of platform is mainly composed of soft soil,foundation pit excavation led to soil and supporting structure creep deformation of pit,reducing passive earth pressure before retaining pile,adding the pile deformation.Therefore,in deep soft soil foundation...
