矿山法施工地铁隧道时控制地表沉降、地下管线沉降的施工技术

Construction technique to control ground settlement and underground pipe settlement in bored metro tunnel

城市地铁隧道一般为浅埋,它与山岭隧道相比,主要区别是要考虑隧道施工对周边环境的影响。文章以广州地铁二～三号线客村联络线工程为例,初步总结了城市地铁隧道采用矿山法施工时,控制地表和地下管线沉降的经验,可供类似工程施工时参考。

Compared with mountain tunnel, metro tunnel is shallow buried and the impact of tunnel construction on environment should be considered. Taking Kecun link project of Guangzhou metro line 2 ~ 3 for example, this paper presents the experience to control ground settlement and underground pipe settlement in bored metro tunnel, which can be taken as a reference for the similar projects in the future.
