胜利黄河公路大桥震害预测研究

STUDY ON THE PREDICTION OF SEISMIC DAMAGE IN SHENGLI YELLOW RIVER BRIDGE

摘要: 桥梁是生命线工程的重要组成部分, 对桥梁作出符合实际的震害预测意义重大。以胜利黄河公路大桥为例, 介绍了经验统计法、规范校核法、Push-over方法、大跨度桥梁定性和定量分析等桥梁震害预测方法。分别用Push-over(推倒分析)法和大跨度桥梁定性与定量相结合的震害预测方法对胜利黄河公路大桥进行了震害预测评价。

Abstract: Bridges are an important part in Lifeline Engineering, and it is significant to predict the seismic damage correctly.Some prediction methods used in Shengli Yellow River Bridge are introduced here, such as experiential statistics method, criterion proofread method, Push-over method and quantitative and qualitative analysis for huge span bridge.The seismic damage in Shengli Yellow River Bridge is evaluated with the last two methods.
