摘　　要：隧洞致灾构造是地质灾害发生的内在条件,决定了隧洞施工地质灾害类型、范围、危害程度等;致灾构造成灾模式研究是致灾构造成灾机理研究的基础。滇中长大引水工程隧洞占比高、工程地质条件复杂,极易发生塌方、突涌水、突涌泥地质灾害。针对滇中长大引水隧洞地质特征,分析其典型致灾地质构造,对其物性特征及成灾模式进行研究,从而提出针对性的隧洞致灾构造预报技术,为隧洞地质灾害风险防控提供理论依据及施工指导。The disaster-causing structure of the tunnel is the internal condition for the occurrence of geological disasters,which determines the type,scope and degree of geological disasters in tunnel construction.The research on the disaster-causing structure is the basis of the research on the disaster-causing mechanism.Due to the high proportion of tunnels in Central Yunnan water diversion project and complex engineering geological conditions,geological disasters such as collapse,water inrush and mud inrush are very easy to occur.According to the geological characteristics of the long tunnels in Central Yunnan water diversion project,this paper analyzes its typical disaster-causing geological structures,studies its physical characteristics and disaster-causing modes,and puts forward targeted prediction technology of tunnel disaster-causing structure,so as to provide theoretical basis and construction guidance for prevention and control of geological disaster risks in tunnelling.
