摘　　要：花岗岩区地质灾害主要以滑坡、崩塌为主,其土质边坡的稳定性受节理裂隙、物质成分、结构构造、水理性质等因素控制,主要取决于残积土中原生与次生结构面的空间组合。作者通过分析研究花岗岩残积土的物理特性,阐述了花岗岩残积土的边坡稳定性和地质灾害发育特征,对此类土质边坡的防治具有较好的指导意义。The main geological hazards in granite area are landslide and collapse.Controlled by joint fissure,material composition,structure and water physical properties,the stability of soil slope mainly depends on the spatial combination of primary and secondary structural planes in residual soil.By analyzing and studying the physical features of granite residual soil,this paper expounded the slope stability and geological hazard development features of granite residual soil,which had a good guiding significance for the prevention and control of such soil slope.
