基于ABAQUS的分离卸荷式板桩码头受力特性

Research of Mechanical Characteristics for Sheet Pile Wharf with Separated Relieving Platform Based on ABAQUS

针对分离卸荷式板桩码头结构的受力变形特性,利用ABAQUS软件进行有限元数值模拟,从卸荷承台与胸墙间距、桩基截面尺寸和桩基排数3个方面对分离卸荷式板桩码头的受力变形特性进行研究,结果表明,加大桩身截面横向尺寸对前墙和桩基的受力变形特性影响较小,适当减小卸荷承台与胸墙间距、选用双排桩结构等可以改善码头受力变形特性,为工程实际提供一定参考依据。

Sheet pile wharf with separated relieving platform is so complex with relatively few engineering applications that characteristics of stressed deformation lacks deep study. This paper researches it's stressed deformation by the finite element numerical simulation of the sheet pile wharf with separated relieving platform with ABAQUS,including the aspects that the space between relieving platform and sheet pile wall,cross-section of the piles and row number of the piles. The results indicate that the increasing pile transverse size of cross section has a slight effect on the characteristics of stressed deformation for the front wall and the piles. Appropriately,reducing the space between relieving platform and the sheet pile wall and choosing structure with double-row piles can significantly improve the stress and deformation properties of the sheet pile wall. This provides a theoretical basis and reference on the future practical applications.
