摘要
高桩码头前后沿同时系靠泊会增加后沿船舶撞击力,使码头结构的横向位移及桩基内力发生变化,针对其受力特点,采用ROBOT对两侧系靠泊的高桩码头受力特性和变形进行数值模拟分析,验证了ROBOT对实际工程计算的适用性。通过较为完整的荷载组合计算分析,指出:对于两侧系靠泊的高桩码头后沿撞击力的增加使码头的横向位移变大,且对直桩的弯矩和剪力影响很大,在设计中应引起足够重视。
The back porch ship impact force will be added on the high-piled wharf under the simultaneous operation of the apron mooring and back porch berthing,and the transverse displacement and the pile foundation inner force of wharf structure will be changed as well.According to the mechanical characteristics,the ROBOT numerical simulation is used to analyze the mechanical characteristics and the deformation of the both-sides-mooring-berthing high-piled wharf.The applicability of the actual engineering ROBOT calculation is validated,and according to the load combination by more complete calculation and analysis,it is pointed out that for the both-sides-mooring-berthing high-piled wharf,the added back porch impact force has a great influence on the bending moments and shear of straight piles,and the transverse displacement of the wharf will be lager,so we should pay more attention to the structural design of the high-piled wharf.
