| Abstract: | 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. |
