DYNAMIC ANALYSIS MODELS OF BRIDGE PIERS IN COLLISION WITH SHIP CONSIDERING THE COMBINED EFFECT OF PILE-SOIL
Based on the theory of Timoshenko, the dynamic analysis models of bridge piers in collision with ship was established under the consideration of the combined action of pile foundation with soil, and transient lateral dynamic responses were researched. According to the assumption of the combined effect of pile-soil subject to Winkler elastic foundation, the interaction between pile and soil was simulated applying elastic coefficient and damp coefficient of the pile side soil. The dynamic differential equations were deduced by Hamilton principle and solved by applying the integral transformation method. In this way, sorts of transient dynamic responses of bridge piers in time domain were obtained. Several useful conclusions were obtained by investigating the effects of impact location, foundation scouring depth, pile length and shear-wave velocity of the soil on transient lateral dynamic responses of the bridge piers.
