摘要
2020年8月甘肃陇南地区出现连续暴雨,当地国省干线公路遭受不同程度水毁病害,其中80%以上为路基病害,严重影响当地公路正常运行。本文基于对陇南地区水毁路基病害的调查,分析了临河路基垮塌、路基边坡变形及路基沉陷等典型病害的变形特征与原因,在此基础上提出各种针对性的处治对策。
In August 2020,there was a continuous rainstorm in Longnan,Gansu.The local trunk highways suff ered from varying degrees of water damage,of which more than 80%were subgrade diseases,which seriously aff ected the normal operation of local roads.Based on the investigation of fl ood damaged subgrade diseases in Longnan,this paper analyzes the deformation characteristics and causes of typical diseases such as subgrade collapse,subgrade slope deformation and subgrade settlement,and puts forward various targeted treatment countermeasures.
