| 摘 要： | 通过介绍齐岳山隧道＂＋629＂溶腔综合治理手段,通过从开挖施工期间准确探测溶腔,前期放水试验,后期补充勘探,平导贯通后＂释能降压＂施工,到爆破泄水和结构物施工等方面的详细介绍,为类似的岩溶隧道施工积累了一点经验。尤其在进行＂释能降压＂施工时,避免了类似宜万铁路其他隧道在泄水施工时对隧道内各种设施、设备的影响,真正做到＂完全释能＂后在进行开挖施工时,泄水未对隧道其他施工造成任何影响。

| Abstract: | Through the introduction of comprehensive treatment measures in +629cavern of Qiyueshan Tunnel,this paper accumulates some experience for similar Karst tunnel constructions,which includes accurate detection of the cavern during the excavation period,dewatering test at the earlier stage,complementary detection at the later stage,energy release and pressure reduction construction after the completion of parallel guiding adit,as well as blasting sluicing and construction of structural works.In particular,durin... |
