【摘要】：由于淤泥质软土强度低、含水率高、压缩性大、流变性显著等特点,软土地基上的基坑工程开挖风险较大,其支护方案的选择对工程的造价、进度、质量影响明显,甚至成为工程能否顺利实施的关键。介绍了上海滨海地区淤泥质软土的特点,并结合浦江镇4个超大型基坑的工程实践,对常用基坑支护型式的应用效果进行综合分析比较,旨在为软土地区类似基坑工程的实践提供借鉴和参考。
[Abstract]:Due to the characteristics of low strength, high moisture content, large compressibility and remarkable rheological property of soft soil, the excavation risk of foundation pit on soft soil foundation is great, and the choice of supporting scheme has obvious influence on the cost, progress and quality of the project. It has even become the key to the smooth implementation of the project. The characteristics of silty soft soil in Shanghai coastal area are introduced. Combined with the engineering practice of four super-large foundation pits in Pujiang town, the application effects of commonly used foundation pit support types are comprehensively analyzed and compared. The purpose of this paper is to provide reference for the practice of similar foundation pit engineering in soft soil area.
