摘要
随着经济和社会的发展,车速与交通量均发生了巨大的变化,对于20世纪50到80年代的桥梁,其服役性能退化和使用状况恶化是当前世界各国众多学者重点关注的热点问题。因此对桥梁进行安全分析并采取相应的加固技术具有重要意义。现依托珠海市斗门区莲洲镇上横大桥加固项目,分析其桥梁存在的主要病害,从经济、安全等多方面论证了加固的必要性,最终提出了详细的加固方案,为今后桥梁加固分析与方案采用提供参考。
With the development of economy and society,the vehicle speed and traffic volume have undergone tremendous changes.The deterioration of service performance and service condition of the bridges from the 1 950 s to 1 980 s is a hot issue that many scholars around the world focus on.Therefore,it is of importance to carry out the safety analysis and to take the relevant reinforcement technology for the bridges.Based on the reinforcement project of Shangheng Bridge in Lianzhou Town of Doumen District in Zhuhai,this paper analyzes the main diseases of the bridge,demonstrates the necessity of reinforcement from the aspects of economy and safety,and finally puts forward the detailed reinforcement scheme,which provides the reference for the analysis and scheme of bridge reinforcement in the future.
