摘要
以上海轨交15号线古北路站深基坑工程为例,研究了新建轨道交通车站基坑开挖及降水对既有构筑物结构安全的影响。为确保深基坑施工的安全及既有构筑物的正常使用,从基坑围护结构、地基加固、施工监测等几个方面阐述了对既有构筑物的保护措施。相关研究结果可供类似工程参考。
Taking the deep foundation pit project of Gubei Road Station of Shanghai rail transit line 15 as an example,the influence of foundation pit excavation and dewatering of new rail transit station on the structural safety of existing structures is studied.In order to ensure the safety of deep foundation pit construction and the normal use of existing structures,this paper expounds the protection measures for existing structures from the aspects of foundation pit support structure,foundation reinforcement,construction monitoring,etc.The relevant research results can be used as reference for similar projects.
