复杂因素影响下高桩码头静动力规律研究
Study of static and dynamic law of high pile wharf under influence of complex factors
摘要
Abstract
High pile wharf is widely used in China's coastal areas,and many factors will have adverse effects on its structure.Based on the finite element analysis software PLAXIS and Mohr-Coulomb criterion,a numerical model of bank slope,pile foundation and superstructure of a high pile wharf is established.The internal force and deformation laws of the wharf superstructure under the multiple factor coupling action of panel loading,ship berthing,siltation of sediment and seismic load are analyzed.The analysis results show that the superstructure of high pile wharf has a large horizontal displacement under the action of multiple factors,and the horizontal displacement is more serious under the action of siltation of sediment.At the same time,the seismic load and siltation of sediment are the main factors affecting the safety of the superstructure,and the maximum internal force of the structure occurs at the top of the pile foundation,so it is necessary to pay attention to the structural design of the top of the pile foundation in the design and construction of the high pile wharf.关键词
