春天门隧道地下水保护设计研究
|
摘要
针对复杂水文地质条件下隧道开挖可能加剧地下水疏干,引发居民生产生活地表用水困难的问题,系统地总结了隧道地下水保护设计经验和存在的不足,改变传统山岭公路隧道"以排为主"的设计理念,在春天门隧道设计中首次完全按"以堵为主"的有压隧道进行设计,通过多形式注浆堵水、根据水压分类设置抗水压衬砌、地表水体防渗和引水回灌等综合措施,地下水保护取得了较好的成效,为山岭公路隧道地下水保护设计提供了示范。
To solve the difficulty that tunnel excavation under complex hydrogeological conditions may aggravate groundwater dredging and cause shortage of water production for residents, this paper systematically summarizes the experience and shortcomings of tunnel groundwater protection design. The design concept of "mainly draining"in traditional mountain road tunnels is changed for the first time in Chuntianmen pressure tunnel,which is designed through the whole tunnel mainly by grouting to block water.which groundwater is protected by multiple forms of grouting,lining against water pressure according to water pressure classification,surface water body seepage prevention and building tunnel water diversion system to the residential area,etc. This paper provides a good demonstration for groundwater protection of mountain road tunnel.
