摘　　要：大支坪隧道岩溶发育强烈,水文地质条件和地质构造复杂,施工难度大。帷幕注浆技术适用于富水断层带和软弱围岩隧道施工,本文主要从大支坪990溶腔的施工、灾害治理措施进行了比较详细的介绍,可为同类型工程提供经验借鉴。The karst is strongly developed in Dazhiping tunnel, where the hydrogeological condition and geological structure is complex, so the construction is difficult. Curtain grouting technique is applicable to water-rich fault zone and weak rock tunnel construction, This article mainly introduces the construction and disaster treatment of Dazhiping 990 cavity in detail, which can provide experience for similar engineering.
