摘　　要：由于山区高速公路受地形条件的制约,在选线过程中常采用隧道方案穿越山岭。山区高速公路隧道地形起伏大、条件复杂,面临断层、岩溶、高地应力、瓦斯等不良地质,可能出现涌水、塌方、大变形、岩爆等地质灾害,若处治不当不仅造成安全质量事故、增大投资、影响工期、后期的运营,甚至会造成不良的社会影响。以某山区高速公路特长隧道为例,探讨复杂地质条件下公路隧道塌方涌水原因分析及处治措施。Due to the constraints of terrain conditions on mountainous highways,tunnel schemes are often used to cross mountains during the route selection process.The terrain of mountainous highway tunnels is undulating and complex,facing unfavorable geological conditions such as faults,karst,high ground stress,and gas.Geological disasters such as water inrush,collapse,large deformation,and rock burst may occur.Improper treatment not only causes safety and quality accidents,increases investment,affects construction period,and later operation,but also has adverse social impacts.Taking a long highway tunnel in a certain mountainous area as an example,this paper explores the causes and treatment measures of collapse and water inrush in highway tunnels under complex geological conditions.
