摘　　要：通过地质调绘等综合工程地质勘察方法,查明高边坡范围及地形地貌、地层岩性和地质构造、地下水条件、降雨、地震、昼夜温差变化、冰雪冰融、不合理的边坡开挖、岩石风化等工程地质条件和气候条件,确定高边坡的变形机理,结合抗剪强度等试验资料及力学指标反算和既有工程经验参数综合分析选用,计算、评价和分析其稳定性,为高边坡治理提供了必要的设计依据。With the method of comprehensive engineering geological investigation like geological surveying and mapping,the paper finds out the range and landform of high slopes,stratum lithology and geological structure,groundwater conditions,rainfall,earthquake,changes in temperature differences between day and night,melting snow and ice,unreasonable slope excavation,rock weathering and other engineering geological conditions and climate factors so as to confirm the deformation mechanism of high slope deterioration.By combining with shear strength calculated by test data and mechanics index as well as comprehensive analysis and selection of existing engineering experience parameters,which can be used in calculation,evaluation and stability analysis,the paper lists the design principles for the need of high slope treatment.
