Reviewing the several main problems of dynamics in antiseismic calculation,the dynamic analysis of singe and multi freedom systems under the seismic action,the method for solving the self vibration period and vibration type of structure were expounded in the paper,the dynamic model and calculation scheme for the seismic calculation of overhead sloping wharf were raised for the reference of design.

According the characters of sloping wharf in Three Gorges Reservoir Region and the service conditions of embedded anti-slide pile,a new reinforced plan used embedded anti-slide pile was proposed for the wharf slope.
