地下水对地铁工程的影响及防治对策研究

Influence of Underground Water on Metro Engineering and Prevention and Control Countermeasures

周期较长以及工程量比较大是地铁工程比较明显的属性,地铁工程进行施工时的环境多种多样,但多数情况下是线路在地下水位之下。在建设地铁工程时,隧道的稳定性,隧道底,隧道管涌隆起稳定都与地下水有重要的关系。地下水会增加施工难度,尤其是在复杂的地质环境,以及地下管线密集的地方,地下水会使地面产生沉降,从而会威胁施工周围的其他建筑。所以在地铁工程施工时,要加强勘察施工地点,要积极防御地下水,管理好地下水资源,保护周围的建筑,使地铁工程有序的安全进行。

The Long period and huge engineering quantity are the obvious property for the subway engineering.The construction environment of subway engineering is various, but most of the lines are under the water level.In the construction of subway project, the stability of tunnel and the formation of basement uplift and piping have an important relationship with groundwater.Thus,groundwater will increase the difficulty of construction,especially in the complex geological environment, as well as the places with intensive underground pipelines.Groundwater will make the ground subside, as a result it will threaten the other buildings around the construction.Therefore, in the subway construction, it is necessary to strengthen the investigation to construction sites,and defend the groundwater actively.Futhermore, in order to make the subway project operate orderly and safely.We have to manage groundwater resources and protect the surrounding buildings.
