基于遗传算法的高桩码头新型分缝结构优化设计

针对高桩码头使用过程中分缝结构常出现裂缝甚至破损的问题,以浙江省某高桩码头作为研究对象,以ANSYS软件作为有限元分析工具,在施加位移约束的工况下,采用遗传算法对分缝结构的尺寸和形式进行优化设计,得到新型分缝结构的设计参数。经ANSYS建模并施加作用力荷载验证,结果表明:新型分缝结构具有缝齿和缝槽间相互作用力、弹塑性变形以及横向错动位移小的优点,能够有效保证码头分缝结构的安全。

Optimization on new joints structure of high-pile wharf based on genetic algorithm

To counter the problems of crack or breakage of high-pile wharf joints structures during operation,we take a high-pile wharf in Zhejiang province as the research object and ANSYS as the FEA tool to optimize the size and type of joints structure with displacement constrained and using the genetic algorithm and get the design parameters of a new joint structure.After modeling and applying force loads of ANSYS,we obtain the result which shows that the new joint has a smaller interaction force between the seam teeth and slots,a smaller elastic-plastic deformation and a smaller lateral dislocation displacements,which can ensure the safety of joints effectively.
