摘要
通过国内外桥梁的使用现状及某大桥主桥的缺陷行为分析,说明桥梁全寿命设计研究的必要性。基于桥梁结构全寿命周期的总体性能最优的设计理念,分析了目前国内外全寿命研究在耐久性、防腐蚀、寿命周期成本分析方法等的主要成果及有关问题。
Through analysis of the current operation status of several bridges at home and abroad and the defect performance of main bridge of a bridge, the necessity of life cycle design research of bridges is illustrated and on the basis of the design conception of the optimal overall performance of life cycle of bridge structures, the principal achievements of and the related issues on life cycle design research of bridges at home and abroad in aspect of their durability, corrosion resistance and life cycle cost analysis method are analyzed as well.
