超限船舶荷载作用下高桩码头损伤数值分析
Numerical analysis of high-piled wharf damage under over-limit ship load
摘要
Abstract
With the influence of factors such as the prosperity of the marine economy and the trend of large-scale ships,improving berth capacity has become a choice for many wharves.In order to effectively understand the potential of the wharf,a simulation numerical model is established using ANSYS/LS-DYNA large-scale finite element software by comprehensive consideration of the interaction between ships,structures and soil for the high-pile wharf with a large current inventory.The JHC model and linear reinforcement model are introduced to describe the nonlinear deformation and failure of the wharf and hull under different ship loads.Fifteen combined working conditions of various ship masses and impact velocities are designed to research on the impact force,wharf structural stress and wharf damage evaluation under over-limit impact.The research shows that the impact force peak is closely related to the ship mass and impact velocity,and the influence of impact velocity is obvious.Batter pile inclined towards the direction of the wharf is the main load-bearing component of horizontal loads,and it should be considered emphatically on the reinforcement design of the components that enhances the structural strength of the wharf.Pile foundation design should consider spacing layout to reduce bearing capacity issues caused by pile group effects.The structural damage ratio is proposed,and its fitting formula of structural damage evaluation is established by fifteen combined working conditions.关键词
