摘要
外滩191项目地处上海都市核心区,基坑开挖深度近20 m,周边紧邻多幢历史保护建筑,环境保护要求极高。介绍了该基坑工程的逆作法设计内容,包括总体方案设计、围护结构设计、水平支撑体系设计、竖向支承系统设计等,针对周边特殊环境进行了数值模拟计算,并对主要监测结果作了分析。设计方案的有效实施使得该基坑工程得以顺利安全完成,对类似环境条件下的深基坑工程设计与施工提供了借鉴。
The foundation pit of Bund 191 Project is located in the center of Shanghai and its excavation depth reaches 20 meters.Protection of the surrounding environment is very strict as many protected buildings are around the excavated site.The design of the top-down method for the project is introduced,including the schematic design,retaining structures,horizontal and vertical support systems,etc.The numerical simulation of surrounding environment is also made and the main monitoring results are discussed.The effective execution of the design scheme makes the foundation pit be completed safely,and it can be used as a reference to the design and construction of other deep foundation pits with similar surrounding environment.
