Abstract: A slope of Qinglong Mountain in Wuhan City is presented in this paper as case history of the slope stability analysis. The factor of safety of the slope is analyzed. The deformation, the damage mechanism, and the damage mode of the slope are evaluated. The slope management plan of “slope shaping + lattice beamed ground anchors + drainage measures + slope vegetation + monitoring” was utilized based on the analytical results. The actual conditions of the slope, the management plan and the slope remediation plan are introduced in detail in this paper. The factor of safety against the mitigation slope stability is estimated. The results showed that the treated slope is in a stable state under heavy rainfall conditions. The slope monitoring results show that the vertical accumulated settlement and settlement rate of the slope are within the tolerable range. After the treatment, the stability of the slope has been greatly improved. This study can provide a reference for the reinforcement design of similar slopes.
