| 摘 要： | 杭州西湖文化广场ABCDE区超大面积深基坑周边环境复杂，受制约条件众多，施工中运用土力学基本原理，提出支撑相对封闭的概念和保留被动土带，通过合理设置支撑施工缝，划分支撑封闭区域，形成立体交叉作业等行之有效的技术，提高了挖土工效，有效地控制了基坑变形，同时降低了施工成本。

| Abstract: | The super-sized foundation pit of the West Lake Cultural Plaza in Hangzhou has a complicated peripheral environment and restricted by lots of factors. A concept of relatively-closed support and preserving the excavated earth zone was proposed in the process of construction on the base of the fundamental principles of soil mechanics, By applying some effective technologies such as reasonable arrangement of construction joint support, division of closed supporting area, cross operation and etc. the earthwork efficiency was improved, pit deformation effectively controlled and the construction cost reduced at the same time. |
