摘　　要：本文在分析杭瑞高速砂性土路基病害类型和成因的基础上,依据路肩加固+坡面防护+坡脚加固+排水的原则,提出了三种砂性土路基病害养护处置方案,并通过施工难易程度、同类工程效果对比等对三种方案进行比选,最终确定路肩注浆+码砌草袋+坡脚加固+排水综合处理措施作为该路基病害养护处置推荐方案。Based on the analysis of the defect of sand-soil subgrade in Hangrui Highway, we put forward three maintenance and disposal plans depending on the principle of shoulder reinforce, hill slope protection, slope toe strengthening and drainage. Then we compared the three plans to confirm the optimum one, which was consist of shoulder reinforce, straw bag piling up, slope toe strengthening and drainage.
