水平集中力在无梁板式高桩码头中的分配

Distribution of horizontal force in bents of high-pile wharf without beam

针对无梁板式高桩码头内力计算方法的问题,分析无梁板式高桩码头排架内力并进行水平集中力的分配系数的研究。采用ANSYS有限元软件进行数值模拟,得出水平集中力在不同跨数与排架间距的无梁板式高桩码头中的分配系数。结果表明:该横向分配系数与现行规范中高桩梁板式码头横向分配系数进行比较均偏小,横向分配系数最小偏差1.8%,最大偏差39.6%。横向分配系数随着横向排架间距的增加而增大,当纵向排架间距、沿纵向跨数或沿横向跨数增大,则水平力横向分配系数减小。

Aiming at the calculation method of internal force of high-pile wharf without beam,we analyze the internal force of the high-pile wharf without beam,and study the distribution coefficient of horizontal concentration.Using the ANSYS finite element software for numerical simulation,we obtain the distribution coefficients of the horizontal concentrated force in the high-pile wharf without beam with different span and bay spacing.The results show that the distribution coefficients of the horizontal concentrated force in the bents of high piled wharf without beam are less than the normative values.The minimum deviation between the two is 1.8%and the maximum deviation is 39.6%.The horizontal distribution coefficients are essentially increased as the space between transverse bents increases.The distribution coefficient of horizontal concentrated force decreases when the number of along-longitudinal span or the number of along-transversal span increases.
