地铁黄土隧道渗漏水的防治

Prevention Methods for Water Penetration in Subway Loess Tunnel

地铁隧道的防水工程是地铁建设中质量控制的关键环节之一。它能有效地保证结构的使用寿命,减少地铁渗漏,防止地铁沿线地面的下沉。介绍了西安地铁2号线永宁门站—南稍门站矿山法暗挖区间隧道的渗漏水预防及治理,以供类似地铁区间黄土隧道渗漏水的防治作参考。

Waterproof engineering is one of the key parts in subway construction, because it could effectively guarantee the service lifetime of structure, reduce the penetrated wa- ter due to subway leakage, and prevent ground settlement along the subway line. Taking a section （Yongningmen Station -Nanshaomen Station） on Xi＇an Subway Line 2 as an example, which was built on mine excavation method, the tunnel leakage prevention and disposal measures are introduced, this case study may provide certain references for similar projects.
