摘要
以某国际集装箱码头为例,利用ABAQUS有限元分析软件,采用Mohr-coulomb准则,建立了高桩码头与土相互作用的三维数值模型。分析在不同回淤深度下对桩基的影响情况。分析结果表明:高桩码头桩后回淤对结构产生不利影响。当回淤深度大于3 m时,在距离桩顶2 m位置处,桩基的拉应力最大值大于抗裂应力,结构出现裂缝。
Based on an international container terminal,ABAQUS finite element software is combined with Mohr-Coulomb criterion to build 3D numerical model for the interaction between the piled berth structure and soil,and analyze the influence of different siltation depths on the pile foundation.The results show that the siltation is harmful to piled berth structure.When the siltation depth is more than 3 m,the maximum tensile stress of pile foundation 2 m away from the pile top is greater than the crack-resisting stress,and then the structural crack occurs.
