摘要
该文以武广高速铁路陈村水道四线铁路特大桥作为工程背景,建立有限元模型,进行地震响应分析,验证了安装铅芯橡胶支座(LRB)作为隔震装置的效果,并采用正交设计和功率系数法对铅芯橡胶支座进行了参数优化,提出了一种通用的LRB选择方法。
Taking Chencun Water Curse Super-large Bridge in Wuguang Express Railway as the engineering background,the article establishes the finite element model and carries out the earthquake response analysis,verifies the effect of installing the lead rubber bearing(LRB)as the earthquake isolating device,uses the orthogonal design and power coefficient process to carry out the parameter optimization of LRB,and puts forward a common LRB selection method.
