隧道地下水处治的国内外研究现状分析

为深入研究隧道设计、施工面临的地下水处治难题，为高压富水隧道设计、施工提供理论依据，对隧道地下水处治技术的现状进行分析。不同部门在不同时期和社会经济条件下，提出了不同规范和地下水处理措施。针对隧道工程设计、施工过程所遭遇的地下水问题，尤其是隧道衬砌水压力荷载问题，各行业部门在隧道(洞)工程支护结构设计中对富水地层地下水压力对支护结构的影响认识并不一致，尤其是对外水压力能否折减仍存在一定争议，对地下水作用的认识仍未达成共识。为此，对隧道地下水问题从概念和方法上进行研究，在研究现状及存在的主要问题分析基础上，提出了下一步研究思路。

Analysis on State-of-art of Ground Water Treatment of Tunnels in China and Abroad

The state-of-art of ground water treatment of tunnels is analysed,so as to make further study on the ground water treatment issue often encountered in the design and construction of tunnels and to provide theoretical basis for the design and construction of high-pressure water-srich tunnels.Conclusions drawn are as follows： different standards and different ground water treatment technologies are proposed by different authority departments at different time and under different socio-economic conditions;experts from different authoritiy departments hold different views on the effect of ground water pressure on the lining structures of tunnels in water-rich zones,especially they hold different views on whether the external water pressure can be reduced or not;the experts also have different opions on the effect of ground water.Therefore,the ground water of tunnels should be further studied in terms of concept and method.The principle for further studies on the treatment of tunnel ground water is proposed.
