摘　　要：通过对因开挖导致溶蚀峰丛斜坡陡坡段出现破坏裂缝影响区域的补勘,获取破坏区主要岩土力学参数,并借助简化Janbu法对夹炭质泥岩软弱层的溶蚀峰丛斜坡进行滑移稳定性分析,采用反算法反算已滑坡裂缝区的抗剪强度指标,用于指导边坡修复和加固,同时给予安全合理的支护建议,以期为类似边坡失稳和支护问题提供科学的参考依据。By conducting a supplementary survey of the affected area by the failure cracks in the steep slope of the dissolution peak cluster slope caused by excavation,the main geotechnical parameters of the damaged area are obtained.And this paper analyzes the slip stability of the dissolution peak cluster slope in the carbonaceous mudstone soft layer by using the simplified Janbu method.The inverse algorithm is used to calculate the resisting shear strength index of the landslide crack area,which is used to guide the repair and reinforcement of slope.At the same time,some safe and reasonable support suggestions are given in order to provide scientific reference for similar slope instability and support problems.
