基于p-y曲线法的高桩码头全结构段和单排架模型对比研究
|
摘要
以某钢筋混凝土高桩梁板结构为例,基于p-y曲线法,采用ANSYS建立了全结构段和单排架模型。施加相应荷载组合,对两种模型的桩基内力进行了对比。通过调整单排架中船舶撞击力在排架中的分配系数,对比单排架的桩基和横梁内力与全结构段的误差。所得结果说明,规范中规定的横向水平力在排架中的分项系数不适用于三维有限元梁板结构。结论对高桩码头内力计算有参考价值。
Taking a reinforced concrete slab and beam structure as an example and based on the p-y curve method, a full-structure segment model and a single-row model are established using ANSYS. The corresponding load combinations are applied to compare the internal forces of the pile foundations of the two models. By adjusting the distribution coefficient of the ship's impact force in the single-row frame structure, the differences between the internal force in the single-row frame structure and that in the full-structure segment are compared.The results indicate that the code-specified distribution coefficients of the horizontal forces in the single-row structure do not apply to three-dimensional finite element slab and beam structures. The conclusion has reference value for the internal force calculation of high-piled wharves.
