| 摘 要： | 上海、江浙等地深基坑开挖范围内常见有砂质粉土和淤泥质粉质粘土等不良工程地质，通常情况下，基坑开挖施工时设计需要回筑换撑。通过对杭州地铁1号线工程闸弄口车站基坑围护变形、支撑轴力等监测数据的分析，经过验算，适时提出取消换撑施工工艺。工程实践证明，充分利用信息化施工手段并结合实际情况，取消换撑可以大大提高施工效率，加快施工速度并取得较好的经济效益和社会效益，对于类似条件下的深基坑施工具有参考借鉴意义。

| Abstract: | Sandy silt and mucky silt clay were often encountered in deep excavation in Shanghai, Jiangsu Province and Zhejiang Province, support replacement is designed to be done in this case. But by the analysis and checking on the monitoring data of excavation enclosure deformation and support axial-force in a station of 1# Line of Hangzhou subway, support replacement was stopped using. By the engineering practice, it was proved that with the combination of information construction and practical situations, construction efficiency was largely promoted without support replacement, which could be the reference for the similar deep excavation engineering. |
