摘　　要：根据检测报告,台州发电厂高桩码头桩基、上部构件存在不同程度损坏情况。由于码头处于河道扩大段,淤积严重,为探讨岸坡淤积对码头安全性影响,本文运用ABAQUS软件,以M-C材料来模拟土体的弹塑性性质,采用梁单元模拟桩基,横梁结构,根据实际岸坡线,建立桩-土相互作用二维有限元模型,分析了淤积自重作用下对桩基产生的内力与变形,计算结果表明在淤积自重作用下,码头有向海侧移动趋势,后排桩基下部受力较大,但桩基承载力富余量充足,码头受力处于安全状态。According to the report, Taizhou power plant high-pile wharf piles, upper structures exists different degrees of damage. Due to the wharf in river expanded paragraph, silting-up seriously, for discussing the security effect of bank slope deposition on terminal, M-C material is used to simulate elas-toplastic properties of soil body by using ABAQUS software, beam element is used to simulate piles, beam structure, according to actual bank slope line, two dimension finite element model about interaction of piles-soil is established, intemal forces and deformation of piles is analyzed under gravity load of siltation, calculation results show that under gravity load of siltation, terminal has the trend of moving to sea side, back piles lower part internal forces are considerable, pile bearing capacity is surplus, the terminal is in a security condition.
