摘　　要：陡斜坡路基作为山区高速公路的重要内容,一直是国内外工程技术人员和相关学者关注和研究的重点。针对国内陡斜坡路基病害时有发生的现状,该文以山区高速公路富水陡斜坡路基为研究对象,通过对国内典型路段富水陡斜坡路基病害形成过程、病害形态和影响因素的深入分析,陡斜坡地貌、挡墙基础软质岩持力层、岩土体裂隙及软弱结构面、水体和施工质量等是诱发山区高速公路富水陡斜坡路基病害发生的关键原因。基于此,提出了一种既可规避前期勘察设计风险,又可消除后期施工质量缺陷的山区高速公路富水陡斜坡路基建设关键技术。As an important part of mountainous expressway, steep slope subgrade has always been the focus of research and attention of engineering technicians and relevant scholars at home and abroad. Aimed at the current situation of steep slope subgrade diseases in China, this paper takes the water-rich Steep Slope Subgrade of mountainous expressway as the research object, through the in-depth analysis of the formation process, disease form and influencing factors of the water-rich steep slope subgrade diseases of typical sections in China, steep slope landform, soft rock bearing stratum of retaining wall foundation, rock and soil cracks and weak structural plane, water body and construction quality are the key reasons for the occurrence of subgrade diseases on water-rich steep slope of mountain expressway. Based on this, a key technology of water-rich and Steep Slope Subgrade Construction of mountain expressway was proposed, which can not only avoid the risk of preliminary investigation and design, but also eliminate the quality defects of later construction.
