| This study investigates the bedding rock slope on the north side of Qingming Mountain in Suzhou. The finite difference method (FDM) was employed to calculate the slope stability factors under the conditions of self weight, heavy rainfall, and earthquake. Integrated with slope boundary conditions and field monitoring data, the slope stability was analyzed, its failure mechanism was revealed, and corresponding treatment and reinforcement measures were proposed. The results indicate that under heavy rainfall and earthquake conditions, the slope stability decreases significantly, with shear failure occurring on the slope surface and tensile cracks developing at the rear edge. The displacement primarily manifests as sliding along the weak interlayer, with the shear exit located above the No. 30 electric tower, posing a considerable threat to the tower. Consequently, an integrated reinforcement system using anchor cables and lattice beams was implemented. Additionally, drainage ditches were installed along the slope crest, the inner side of the No. 30 tower, the slope toe, and longitudinally along the slope body. Post treatment assessment shows a significant improvement in slope stability. |
