Relying on the first-stage project of Funing port in Yunnan province,we establish a three-dimensional finite element model of the overhead sloping wharf.Based on the water-rock interaction,considering the degradation damage of bank slope’s rock and soil mass under water level cycles circulation in the mountainous rivers,we obtain the bending moment,the shear and axial force of the pile and track beam qualitatively.The result can be a basis for further studying the whole performance and mechanical degradation characteristics of the overhead sloping wharf.It can also provide recommendations for monitoring and protection practical engineering after operation of the terminal at the reservoir area.
