摘要
上海世博会配套工程500kV地下变电站为全地下(4层)工程,地下建筑外径130m,开挖深度34m,采用逆作法施工。采用新工艺、新技术进行抓铣结合地下连续墙施工、高垂直度超长钢管立柱桩施工、超深地下空间逆作取土、承压水控制、逆作作业环境措施以及周边环境的实测。采用理论分析与实测相结合的办法,通过全过程的信息化施工,综合应用多项施工技术措施,确保了该工程取得圆满成功,使工程在节约资源、减小对周边环境影响等方面取得良好的社会和经济效益。
The 500kV transformer substation,as entire underground structure with 4 stories,is an important auxiliary projects of Expo 2010 Shanghai China,and it adopts reversed construction method. New process,new technologies are used in construction,such as construction diaphragm wall with grasp-milling union,construction of super-long steel column-piles with high requirements on verticality,reversed excavation of super-deep foundation,control of underground water and monitoring of surrounding environment. The theoretical analysis and monitoring are combined during the whole process information construction,and the project is successfully completed with various construction measures. Moreover,the projects have gotten fine social and economical benefits in the field of saving resource,reducing influence on surrounding environment.
