在E2地震作用下，分别对采用高阻尼橡胶支座与普通支座的桥梁结构进行时程反应分析，对结构的自振周期及桥墩墩底内力进行对比分析，结果表明，采用高阻尼橡胶支座能使结构自振周期延长，增加耗能时间，减震效果明显。

Under the action of E2 seism, this paper makes a time-history response analysis on the structure of bridge respectively adopting high damping rubber support and common support, and has a comparative analysis on natural period of vibration of structure and internal force at the bottom of bridge pier. It is indicated from the results that adopting high damping rubber support will prolong the natural period of vibration, increase the period of energy consumption, and the vibration-suppressed effect is obviously good.
