板桩对框架结构海堤隔离堤后堆载作用的有限元分析

Finite Element Analysis of the Isolation Effect of Pile Plank to the Load along the Framed-seawall

结合温州某软土地基上桩基框架结构海堤工程实例,采用MIDAS有限元软件分析了板桩的布置位置、深度和厚度变化对框架结构海堤受力和变形的影响。结果表明,合理选择板桩的布置位置和桩长是框架结构海堤隔离堤后堆载,改善其受力和变形的主要因素。

Combining with engineering case of a framed- seawall with pile foundation built on soft soils in Wenzhou, the comparative analysis of the bearing force and the deformation of the framed-seawall is performed considering the different layout positions , depth and thickness of the pile plank based on the finite element software MIDAS. The results show that the pile plank can isolate the load effectively with reasonable layout and length so that they are the main factors of improving the bearing force and deformation of the framed-seawall. The results can be regarded as reliable reference datum for the design of the framed-seawall.
