建立了刚构体系斜拉桥有限元模型，进行了结构自振特性分析，对设不设置铅芯橡胶支座的2种模型进行了地震响应分析，并对减震支座参数进行了合理性研究。结果表明：刚构体系斜拉桥设置铅芯橡胶支座可以获得良好的减震效果。该结论可供同类型桥梁减震设计参考。%The finite element model of rigid-frame system cable stayed bridge was established ,and the structural natural vibration characteristics and seismic response of two models of setting or not setting the lead rubber bearing were ana-lyzed,also the rationality of bearing damping parameters were studied. The results shown that the lead rubber bearing of rigid-frame system cable stayed bridge can obtain good damping effect.
