摘　　要：通过对挖方边坡进行地质调绘和钻探,结合现场开挖剖面,查明段落内的地层岩性、地质构造、不良地质及特殊性岩土等工程地质条件,重点查明断层厚度、走向、倾向、延展程度等特征,判断其对公路建设的影响,评价边坡稳定性,为该挖方段设计提供工程地质依据。In combination with on-site excavation profiles,the engineering geological conditions of the formation lithology,geological structure,unfavorable geology,and special rock soil and so on within the section are identified through the geological mapping and drilling of excavation slopes.The characteristics of fault thickness,trend,inclination and extension degree and so on are emphatically identified,the impact on the highway construction is judged,and the slope stability is evaluated,so as to provide the engineering geological basis for the design of the excavation section.

关 键 词：挖方边坡 工程地质条件 边坡稳定性 动态监测
