| 摘 要： | 综合混凝土碳化模型、钢筋锈蚀模型,运用随机有限元方法,对既有钢筋混凝土桥梁设计基准期内的结构失效概率、可靠度进行分析,提出综合目标可靠度和维修成本效益的桥梁维修需求预测模型。通过在一座下承式系杆拱桥的应用,进行了维修方案的比选,预测了其在设计基准期内的维修需求,验证了方法的可行性。

| Abstract: | In combination with concrete carbonation model and reinforcement rust corrosion model,the stochastic finite element analysis method is used to predict the time-dependent failure probability and reliability of reinforced concrete bridges in their design life period.The prediction model based on the comprehensive goal reliability and repair cost effectiveness for repair demand of the bridges is proposed,and the feasibility of the analysis and prediction method is verified through comparison of different maintenance schemes and repair demand predictions on a through tied arch bridge. |
