复杂环境条件下深基坑工程实践

Deep Excavation under Complicated Geotechnical and Environmental Conditions

上海北外滩苏宁广场项目基坑工程邻近地铁隧道及历史保护建筑,周边环境条件复杂,环境保护要求高。根据工程特点,以及对地铁隧道和历史保护建筑的保护的要求,从设计和施工方面采取了一系列的针对性措施,并通过周密监测实行"信息化"施工,确保基坑工程及其周边环境在施工期间的安全。

The deep excavation for the Suning Square is located in the north of Shanghai Bund.The proposed deep excavation has a very restrict environmental requirement and complicated geotechnical conditions due to its close approximate to the adjacent metro tunnel and historical buildings.Base on the specific requirements of the project,the metro tunnel and the historical buildings were closely monitored during the construction and these monitoring data were used to guide the exaction construction.The safety of the deep excavation and the adjacent structures were ensured during the construction
