地铁盾构施工对临近隧道底板沉降影响分析

The Settlement Analysis of Shield Construction Impact To the Near Tunnel Floor

随着城市地下交通现代化建设的进程,多条地下铁路在地下立交的情况已越来越多。盾构施工难免会引起已建隧道底板的沉降变化。本文结合一实例,介绍了施工期间的沉降观测方法,对可能引起底板变形的原因进行了分析,对指导类似盾构施工起了实际的指导意义。

With the city s subway modernization process,More and more Transit Railway interchanged underground.Shield Construction will cause settlement in the tunnel floor has been built.In this paper,introducing the settlement observation during construction methods,Analysis to causes of floor deformation that may cause,In order to have actual significance to Shield Construction of the similar guidance.
