摘　　要：目前,国、内外针对水深和水位变幅较大的内河架空直立式框架码头的研究成果不多,针对码头使用过程中主体结构与接岸结构间相互作用的研究就更少。根据这类码头的受力特点,通过在码头前方承台的横梁与接岸结构之间增设弹簧隔振装置模拟接岸结构和码头主体的作用力,利用PLAXIS软件研究不同的水位下降速度对码头主体与接岸结构间相互作用的影响,求得到结构的内力和变形,并在此基础上提出弹簧的刚度系数。By now, a few research results have been acquired in China and abroad, which are for overhead vertical framed wharf along inland-river with larger change ranges of water depth and water level. And few research has been done for interaction of wharf and shore approach during wharfs operation. Based on its stress characteristics, a shock isolating spring is set up between front apron beam and shore approach in order to simulate the interaction of wharf and shore approach. PLAXIS software is applied to study the impact on the above interaction by different water level falling velocities, to get internal force and deformation of structures and put forward spring rigidity coefficient.
