摘　　要：我国西部山区分布大量岩溶,岩溶地区修筑隧道极易发生突水涌泥、隧道大变形、施工坍塌等各类病害乃至事故。隧道与溶洞的相对位置不同,病害的性状也不一样,需要采用的施工应对措施也存在较大差别。本文结合某高速公路隧道穿越岩溶地区的施工经验,分别介绍了溶洞与隧道处于不同相对位置时的施工处治技术,该隧道的施工经验可为今后类似工程施工提供参考。A large number of karsts are distributed in the mountainous areas of western China.The construction of tunnels in karst areas is prone to various diseases and accidents such as water inrush and mud,large tunnel deformation,and construction collapse.The relative positions of the tunnel and the karst cave are different,the characteristics of the disease are also different,and the construction countermeasures that need to be adopted are also quite different.Based on the construction experience of a highway tunnel crossing karst area,this article introduces the construction treatment technology when the cave and the tunnel are in different relative positions.The construction experience of this tunnel can provide reference for the construction of similar projects in the future.
