随着我国高速公路的快速发展，高速公路的修建不可避免要穿越岩溶地区，岩溶路基病害主要体现在路基塌陷和路面沉降，严重影响公路安全和正常使用。以昌金高速公路岩溶路基病害为例，结合覆盖层地质概化模型，分析了岩溶塌陷的机理和成因，根据成因的不同对整治方案进行了比选，提出了相应类型岩溶路基病害的整治方案，可为高速公路岩溶路基病害防治提供参考。

With the rapid development of expressway in the recent years,more construction of expressway will pass through the karst region inevitably. The harm of subgrade karst mainly reflects in the subgrade subsidence and road collapse,which has serious impact on road safety and transportation. This thesis reserch on the mecha-nism of karst collapse with the simplified geological model of overburden ,which used the Karst subgrade dis-eases in Changbo-Jinyushi expressway as examples. After compared different kinds of treatment scheme in ac-cordance with different causes,reasonable treatment measures for Karst subgrade diseases have been deter-mined,which will provide a reference for the similar Karst subgrade diseases.
