盾构法施工隧道的防水浅谈

盾构法已成为现代城市地下铁道或排水隧道等施工的主流方法。而盾构法施工的隧道的防水是一项非常重要而复杂的工作。近些年来，盾构法施工过程中因各种原因，隧道渗漏水非常严重，有上升趋势，某些城市运营中的地铁盾构隧道渗漏水问题也非常突出，甚至影响到了列车的运营。作者根据自己在盾构施工中的切身体会，对盾构法施工隧道的防水进行一下浅析，以供参考。

Waterproofing of Shield-driven Tunnels

Shield tunneling has become one of the dominant tunnel construction methods for modern urban Metro works and sewage works. The waterproofing of the shield-driven tunnels is very important and complicated. Due to various construction factors, the water seepage/leakage of shield-driven tunnels is much serious and has a rising tendency in recent years. The water seepage/leakage of some shield-driven Metro tunnels in some cities is so serious that the operation of the trains is impacted. Based on the field experience in shield-driven tunnel construction, the author introduces the wa- terproofing of shield-driven tunnels.
