杭州软土地区深基坑基底隆起的原因分析

Reasons for the Surface Upheaval of Deep Foundation Pit in Hangzhou Soft Soil Area

以杭州地铁1号线某地铁车站深基坑为分析原型,分别采用日本规范、我国设计规范、模型试验法等5种不同的方法进行基坑基底隆起的计算,并将计算得到的理论值和现场的实际值进行了对比研究。对软土地基深基坑基底隆起的位置及原因进行了分析,并指出类似工程施工应该注意的问题。

Taking a station of Hangzhou Subway Line 1 as the analysis prototype, the surface upheaval of the foundation pit is calculated by adopting 5 methods including Japanese code, China ＇ s code of building foundation design, model test and references and so on , the theoretical value and actual value are compared, the reasons for the surface upheaval of the deep foundation pit in soft soil area are analyzed.
