The analysis on deep foundation pit support case in soft soil area adjacent to historical and cultural relics

以上海静安78号街坊深基坑工程为例,该项目下设地下5层地下室。项目位于上海市静安区,深基坑紧邻中共中央秘书处机关(阅文处)旧址——省级文物保护单位。通过加强围护墙、支撑体系、坑内加固等一系列针对性的设计方案,确保该深大基坑的顺利实施并实现对周边保护建筑的临时保护。通过该工程的成功实施,可以为软土地区复杂环境下深大基坑设计施工提供一定的参考依据。

Taking the deep foundation pit engineering of No.78 Neighborhood in Jing’an,Shanghai as an example,the project located in Jing’an District,Shanghai,included underground 5-storey deep basement,the deep foundation pit adjacent to the former site of the Secretariat of the CPC Central Committee(the Reading Office)-a provincial cultural relics protection unit,through a series of targeted design schemes such as strengthening the enclosure wall,support system,and reinforcement in the pit,ensured the smooth implementation of the deep and large foundation pit and the temporary protection of surrounding protected buildings,through the successful implementation of the engineering,could provide some reference for the design and construction of deep and large foundation pits in the complex environment of soft soil areas.
