【摘要】 简要介绍了城市桥梁的六种震害预测方法。在确定采用哪种方法时,要根据桥梁的结构型式、桥墩材料、墩台高度、基础类型等因素来确定。在详细介绍了回归统计法的基础上,通过实际桥梁的震害与回归统计法的预测进行比较,检验了回归统计法的可靠性。更多还原

【Abstract】 Six methods for seismic damage prediction of bridges in cities are introduced briefly in this paper. To determine which method to be used, some factors should be taken into consideration, such as the kind of bridge structure, the height of piers and abutments,the type of base, et al. The regression method is introduced in detail, and the seismic damage of some bridges is predicted by the regression method. The results are compared with the bridge earthquake damage. The compared results show that the regression method is reliable and can be used in the damage prediction of bridges.更多还原
