摘要
将船舶撞击力作为框架码头排架的主要荷载,重点分析计算框架码头桩基结构在不同水位条件下受船舶撞击时的静力分布情况。计算结果表明:由于码头排架横向的整体刚度较大,虽然处于排架不同位置的钻孔灌注桩直径相同,但内力异很大,近岸侧桩基所受的最大内力可达到码头前沿附近桩基内力的1.8倍甚至更多,可为进一步优化桩基布置和结构设计提供参考。
Ship impact force is defined as main load on the bents used for strengthening frame wharf. Analysis and calculation is made to get static distribution data for the pile foundation structure of the frame wharf being impacted by ship at different water level. The calculation result shows that the lateral stiffness of the bents is higher. Though the diameter of piles is same for the driven cast-in-place piles under different bent, the internal forces are quite different. Maximum internal force of shore-side pile foundation is at least 1.8 times the internal force of pile foundation at front line of the frame wharf, which will provide references for more optimization of pile foundation layout and structural design.
