摘　　要：为研究半成岩类型高边坡的失稳机理和破坏模式,选取兰海高速陇南段某半成岩地层高边坡失稳工点,从工程地质、气象条件、变形特征等多方面对失稳成因进行分析,并根据潜在滑面进行了边坡稳定性计算,据此提出了该高边坡加固治理措施。In order to find out the instability mechanism and failure mode of high slope of semi diagenetic strata,taking the instability of high slope of a semi diagenetic strata in Longnan section of Lanhai expressway as a construction site,the causes of instability are analyzed from engineering geology,meteorological conditions,deformation characteristics and other aspects.According to the calculation of the slope stability of the potential sliding surface,the reinforcement measures of the high slope are put forward.
