摘要
基于日本宫城县冲地震和阪神大地震中高桩码头结构震害调查的结果,分析了2次地震中高桩码头出现震害的原因,探讨了其破坏机理。通过对现有高桩码头结构导入减震橡胶支座后的地震反应分析得出,采用减震支座将使桩上部固定端处的最大弯矩减小到减震前的三分之一,有利于提高高桩码头的抗震能力。
The damage phenomenon of high-piled piers in the two earthquakes are analyzed,based on the investigation of the earthquake damage in Miyagiken-oki and Kobe Earthquake in Japen.And then,the mechanism of fracture was discussed.Through analyzing the dynamic response of the structure before isolation and after isolation,it's obtained that the maximum bending moment of pier foundation will be reduced to 1/3 before isolation,which will improve the earthqauke stability.
