【摘要】 由于旧高桩码头的改造不能依据原有的设计承载力或现有的规范来进行,故需对拟改建码头的基桩承载力重新进行计算,为旧码头的设计和改造提供理论依据。采用ANSYS软件对某高桩码头拟改建后的基桩桩力进行了有限元分析。在数据处理方法上,对主要荷载取了较大的安全系数,对门机吊车产生的移动荷载情况进行了多次的桩力比较,根据计算结果确定基桩的最不利荷载,从而得出最大的桩力设计值。更多还原

【Abstract】 Since the renovation of existed wharves can not be conducted according to the original design load or the existed standards and codes,there is a need to recompute the foundation-pile bearing capacity of the wharf to be renovated,so as to provide a theoretical basis for the design and renovation of the existed wharf.Software ANSYS was utilized to conduct FE analysis of the foundation-pile bearing capacity of the wharf to be renovated.In data processing methods,safety factors big enough for main loads were taken,and the simulation of moving loads for gantry crane were performed to achieve various comparisons for pile forces.Therefore the most adverse loads of piles were determined based on computational results,and then the largest design values of piles were obtained.更多还原
