摘　　要：土岩混合边坡因其物质结构特点而具有多种变形破坏模式。该类边坡既有浅部雨水冲刷水毁、滑塌问题,也有基于土体自身强度较差原因造成的土体圆弧状滑动问题,以及受控于土岩结构面控制的土体整体滑移问题。变形破坏模式的多样性和影响因素的复杂性导致土岩混合边坡在公路建设和后期营运过程中病害频发,严重影响工程建设和运营。对广乐高速公路K181＋580~K181＋790右侧路堑边坡工程地质环境和变形破坏机理进行分析,提出边坡的合理整治措施,取得良好的工程效果。Soil-rock mixed slope has multiple deformation failure modes due to its material and structural features. Such slopes show not only the problems of shallow water damage due to rain wash and slump,but also the problem of arc-shaped slide of soil caused by bad strength of soil and the problem of integral soil slide controlled by soil-rock structural surface. Diversity of deformation failure modes and complexity of influence factors lead to frequent disasters of soil-rock mixed slope during highway construction and later operation that seriously affect project construction and operation. This paper analyzes geological environment and deformation failure mechanism of the slope project on the right cutting of Guangzhou—Lechang Expressway K181 ＋ 580 ~ K181 ＋ 790 and proposes the reasonable treatment measures for the slope and has achieved perfect project effect.
