四川省高县附近斜坡变形失稳灾害尤为严重。本文对斜坡变形失稳的类型，特点、形成原因、影响因素、破坏模式进行了分析，认为软弱岩层岩性。斜坡岩体结构、斜坡类型、岩体节理裂隙、地貌发育为决定斜坡稳定性的五主导因子。经深入研究，以定性定量标准把五因子分别划分为四级。利用斜坡变形模数计算五因子影响斜坡稳定性的权重等。从而获得了一种新的斜坡稳定性评价模式，把它运用于高县县城附近斜坡稳定性评价中，评价结果与实际基本相符。
The slope instability near Gaoxian County in Sichuan Province is particularly serious. This paper analyzes the types, characteristics, formation reasons, influencing factors and failure modes of slope deformation instability, and considers the lithology of soft rocks. Slope rock mass structure, types of slopes, rock joints and fissures, and geomorphology development are the five dominant factors that determine slope stability. After thorough research, the five factors were divided into four levels by qualitative and quantitative standards. The slope deformation modulus is used to calculate the weight of the five factors that affect the stability of the slope. Therefore, a new slope stability evaluation model was obtained, which was applied to the slope stability evaluation near the county seat of Gaoxian County. The evaluation results were basically consistent with the actual results.
