某高桩码头结构行车移动荷载分析

为了研究码头结构在上部刚架行车移动荷载作用下的结构安全性,针对某钢-混凝土混合刚架式高桩码头结构,建立桩基、周围土层、码头平台结构和上部刚架整体三维数值模型,并利用ANSYS有限元软件进行数值模拟.结果表明:码头结构最危险工况为南、北两侧行车同时移动到刚架水侧悬臂端并考虑大车刹车荷载；结构位移、应力及内力对南、北两侧大车同步同向运动工况敏感性较强；桩基轴力均为受压状态,岸侧E排桩体不存在上拔情况.这些认识可为同类高桩码头移动荷载分析和设计提供参考.

Analysis of high-pile wharf under crane traveling load

In order to research the safety reliability of high-pile wharf under the crane traveling load,we take a steel-concrete mix rigid frame high-pile wharf as a study case to establish the whole 3D numerical model,which includes the piles,surrounding soils,structures and the upper rigid frames,and adopt the software ANSYS for numerical calculation.The result indicates that the most dangerous case is that when the north crane and south crane arrive at the cantilever of the water side rigid frame simultaneously;wh...
