【摘要】 从全寿命的角度,讨论了海洋腐蚀环境的钢筋混凝土桥梁结构的全寿命可靠性评估框架以及安全经济决策方法,分析了桥梁结构不同初始可靠度及不同耐久性水平时安全经济决策的方法,并用案例详细说明了改善并提高桥梁结构初始可靠度和耐久性的安全经济决策分析方法和过程。更多还原

【Abstract】 From the point view of lifetime, the principles, methods and thoughts of durability design of Reinforced Concrete (RC) bridges in severe marine environmental conditions are probed into, and a systematic framework of safety appraisal and economic analysis was proposed. The comparing methods for different initial structural reliability and different strategy of maintenance were deeply discussed. A case study was given out for illustration of improving the concrete durability design and procedures of appraising about its safety and cost in lifetime.更多还原
