为了进一步明确平面形状不规则对高桩码头地震效应的影响,以L型平面不规则高桩码头为例,基于美国Northridge地震波,采用ABAQUS有限元软件对比分析了平面形状不规则与规则高桩码头的地震反应,研究了平面形状不规则对高桩码头各桩桩顶水平力、弯矩及结构整体扭转角的影响。结果表明,高桩码头平面形状不规则会导致桩顶水平力和结构整体扭转角的增大,桩基地震破坏数目增加;平面形状不规则高桩码头转角部位桩群水平力峰值普遍较大,且应力复杂,设计中需重点考虑。
In order to further clarify the influence of irregular shape on the seismic effect of piled wharf, taking the L-shaped irregular piled wharf as an example, based on the Northridge seismic wave in the United States, the ABAQUS finite element software is used to compare the irregular shape of the piled wharf The effects of irregular shape on the horizontal force and moment of piles and the overall torsional angle of piles in piled wharfs are studied. The results show that the irregular shape of the piled wharf leads to the increase of the horizontal force and the overall torsional angle of the piles and the increase of the number of earthquake damage. The peak horizontal force of the piles at the corners of the irregularly shaped piled wharf is generally large, And the stress is complex, the design needs to be focused on.
