上跨地铁项目的深基坑工程设计

Design of the Deep Foundation Pit Engineering Above the Subway

本文以南京雨花台区NO.2015G71项目基坑工程为例,介绍了该基坑工程的工程概况和总体设计方案,对上跨地铁提出了针对性的保护措施。实践表明,采取的技术措施能有效控制支护结构及周边环境变形,从而验证了基坑工程设计的合理性,为类似规模和地质条件的深基坑工程提供了新的设计思路。

Taking the project of Nanjing Yuhuatai District NO.2015G71 Project as an example,the general situation and overall design scheme of the deep foundation pit project are introduced,and the targeted protection measures for the upper span subway are put forward.The practice shows that the deformation of supporting structure and surrounding environment can be effectively controlled by adopting the technical measures.The rationality of foundation pit engineering design is verified.This paper provides a reference for other deep foundation pit projects in similar scale and geological conditions.
