Ship Impact Force Analysis and Design Project Selection of Pinghai Bridge

Abstract

Based on summing up the domestic and foreign ship impact force calculation formula, the finite element method was used to establish the Pinghai Bridge analysis model. The pier ship impact force as a reference came from relevant design data, and the finite element calculation and analysis on ship impact were carried out. For there is auxiliary pier and not, the internal forces of main pier, cap bottom of main pier and a single pile under the combinations of ship impact force along and across the bridge direction of Pinghai Bridge were respectively calculated and reinforcement designed. The results show that the section of main pier can meet the force requirements only by the structural reinforcement; under the ship impact loads, saving the auxiliary pier has little effect on the results of section reinforcement of the main tower and the main pier. These conclusions have reference values to some extent for the design plan selection under the action of ship impact force.
