摘要

岩溶灾害严重危及隧道施工的安全,影响施工的进度,是目前国内外隧道建设面临的重点和难点问题。首先对马鹿箐隧道历次涌突水特征进行了分析,主要阐述了超前地质预报技术、水文观测、反坡追排水清淤技术和泄水释能工法等技术在+978溶腔的岩溶水处治中的应用,最后对溶腔揭示后隧道跨越溶腔段的工程处治措施进行了详细介绍。马鹿箐岩溶隧道成功的施工经验,为今后类似隧道工程中大体量高压富水隐伏岩溶问题的处理提供参考和借鉴。

Abstract

Karst disaster is badly endangering the safety of tunnel construction and impedes the construction schedule seriously. In present, it is an important and difficult problem in tunnel construction all over the world. The feature of karst water burst in Maluqing Tunnel is analyzed first, and then advanced geological forecasting technology, hydrological observation, reverse slope drainage technology and water release technology in the treatment for the +978 Karst cave are introduced separately; what is more, disclosure progress and the status after disclosing of the +978 Karst cave are depicted detailedly. Finally, curtain grouting technology for stratum consolidation and pile-cap technology for spanning karst cave after the +978 Karst Cave disclosed are introduced too. Successful experience for the karst treatment in Maluqing Tunnel will provide a reference to the treatment for karst cave with large quantity water during the similar tunnel construction in the future.
