桥梁隔震体系振动台试验研究(III)——测试结果分析

Shaking table test study of bridge isolation system (III)──An analysis of measured results

根据前文所述的测试结果 ,本文主要分析了隔震构造、橡胶支座水平刚度、地震输入频谱特性、地震烈度、输入方向、桥墩高度、桥墩嵌固程度等因素对隔震效果的影响 ,揭示了隔震体系耗散地震能量输入的机理 ,所得出的结论对工程实践具有指导意义。

According to the measured results presented in preceding papers, the influence of isolation construction, horizontal stiffness of rubber support, frequency and direction of earthquake input , seismic intensity and the height and fixing degree of bridge pier on isolation effect is preliminarily analyzed. Moreover, the mechanism of dissipation seismic energy for isolation bridge system is illustrated. The conclusions are of guiding significance for engineering practice.
