| 摘 要： | 已开通运营的铁路隧道底部出现岩溶洞穴,使得线路部分悬空,且存在岩溶洞穴涌水,危及铁路行车安全,致使铁路停止运营。因此,制定合理、科学、有效的线路加固方案,使线路尽快正常开通,对溶洞进行有效的处理以消除安全隐患极为重要。本文根据铁路隧道溶洞结构的具体情况,介绍了隧道内线路加固及溶洞处理方法,对此类溶洞处理提供一些借鉴。

| Abstract: | Limestone cave is found at the bottom of operating railway tunnel.Part of the rail is suspended and water flows into the cave,which has hazarded the railway and causes to stop operating.Therefore,it is essential to step up a reasonable, scientific and effective rail reinforcement scheme to operate the railway and eliminate potential risk.According to the limestone cave structure in tunnel,the paper introduces a method to reinforce the rail and treat the cave in hope of offer some experience to similar limestone cave treatment. |
