| 摘 要： | 马鹿箐隧道地质极为复杂,多次遭遇岩溶溶腔特大型突泥突水,为目前世界铁路建设史上瞬间突涌水量最大的隧道,其工程艰巨程度和安全风险之大实属罕见,受到国内外工程界的高度关注。主要针对马鹿箐隧道"1.21"溃水前后,对PDK255+978溶腔段实行的一系列超前地质预测预报技术进行了详细介绍,并对技术实施过程中的重点和难点进行了分析与研究,总结了针对高压富水隐伏岩溶隧道的综合超前预测预报技术方法和综合的地质分析方法,为今后类似岩溶隧道修建中的预测预报工作提供了借鉴与参考。

| Abstract: | Maluqing Tunnel's geology is extremely complex,faced with several large projecting mud soils and gushing water of the karst caverns.This tunnel has the largest instant gushing water in the present world railway construction history.Therefore,the engineering difficulty and safety risks in this project are rarely seen and received highly attention in the engineering circle domestically and abroad.Targeting at the situations before and after 1.21 Water Burst in Maluqing Tunnel,this paper elaborates in detail a... |
