摘要
闻江寺隧道出口(野梅岗端)为149 m高,强风化90°峭壁,时常掉石块,危险性大,并且隧道内离出口5 m处线路左侧拱腰处有大溶洞,溶洞内有大量泥水。对闻江寺隧道出口溶洞进行研究,通过溶洞处理方案比选,采用回填溶洞、大管棚注浆技术安全出洞。并详细介绍了此方案安全出洞的施工工艺。
The exit of Wenjiangsi tunnel(Yemeigang end)is 149m high,with highly weathered cliffs of 90°,stones often fall,and great danger.In addition,there is a large karst cave in the left arch waist of the line 5m away from the exit,and there is a lot of muddy water in the cave.The exit cavern of Wenjiangsi tunnel is studied in this paper,and the technology of backfill cavern and pipe shed grouting is adopted to safely exit the cavern after the comparison of karst cave treatment schemes.Paper introduces in detail the construction technology of this scheme.
