摘　　要：某高速公路路基在通车后不久发生了路基路面纵向开裂。为了弄清路基路面开裂原因,提出安全可靠的工程治理措施,对路基进行了工程地质补充勘察、路基变形监测、裂缝扩展监测,分析出路基裂缝是由于下卧高压缩性软土层、路基填料性质较差、填筑质量欠佳造成的,提出了基于提高路基整体稳定性和耐久性的工程治理措施。There was the longitudinal crack occured in the highway subgrade shortly after the opening to traffic.The cause of longitudinal crack was found out based on the extra geotechnical investigation,subgrade deformation monitoring and crack extension monitoring,in which the high compressible soft soil under subgrade soil,the poor filling material and the poor quality of construction were main causes,then the related measurement was proposed to improve the integral stability and durability of embankment.
