摘要
基坑开挖易引起周边地层移动,导致邻近地铁车站和隧道发生不可忽视的结构位移。文章以新城大厦二期基坑工程为例,通过对基坑支护结构及南京地铁二号线奥体东站和奥体东站~兴隆大街站区间隧道的变形监测数据进行分析,详细研究了基坑开挖对临近地铁车站和区间隧道的变形影响,得出了一些对类似工程有益的结论。
Due to the excavations, surrounding ground can be easily disturbed, leading to the structure displace which cannot be ignored of the nearby subway station and tunnel. Taking the second stage foundation pit engineering of New City Mansion for example, based on the deformation monitoring data of supporting structure of excavations,the Olympic Station and the Olympic Station-Xinglong Street Tunnel of Nanjing metro line two,the influence of excavation on nearby subway station and tunnel is analyzed. This paper provides a reference for other similar projects.
