The application of dewatering technique in rich water soft soil stratum in metro construction

结合某区间隧道浅埋暗挖法施工中的降水技术 ,从施工难点、降水设计及控制地表沉降的效果等方面进行了分析 ,提出在地下水丰富的条件下 。

Taking the shallow tunneling construction work of one regional tunnel as example the dewatering technique adopted are analyzed from construction difficulties, construction design, ground settlement control and other aspects. Author points out that dewatering construction plays important roles in tunnel construction in rich water soft soil stratum.
