Failure mechanism and stability analysis of bank slope deformation under the synergistic effect of heavy rainfall and blasting vibration

Underwater blasting technique is often adopted to clear away the obstructed reef and dredge-cut in mountainous waterway dredging engineering. However, vibration of underwater excavation riverbed has a certain influence on stability bank slopes. Combined with partial collapse phenomenon regulation project between two dams Three Gorges reservoir area, change pore water pressure unsaturated soil under heavy rainfall increase permanent displacement area are discussed. This paper explains weakening effect infiltration slope. By studying law slope failure deformation separate action coupling action, it found that promotes enlarges soil, which demonstrated accelerated mechanism rainfall-blasting
