The present thesis applied Midas civil to organize a finite element model, and compared the structural responses of the laminated rubber bearing model and the lead-rubber bearing model in earthquake through the structural nonlinear analysis of setting two kinds of bridge model on fundament of the Jianggu Road Bridge of the Jinjiang Highway in Yun Nan Province. According to the comparative analysis, it is found that setting lead rubber bearing model can effectively prolong the structural period and enhance the ductility of the structure. In addition, lead-rubber bearing model improve the structural responses under effects of earthquake obviously, and it is suitable for districts that involve in large intensity of earthquake.%本文以云南晋江高速公路江孤路大桥为依托，利用Midas civil建立有限元模型，通过对分别设置板式橡胶支座和铅芯橡胶支座两个桥梁模型进行结构非线性分析，对比两者在地震下的结构响应。经过比较分析，设置铅芯橡胶支座能够有效的延长结构周期，增加结构延性。明显的改善地震作用下的结构响应，比较适合烈度较大的地区。
