摘　　要：桥梁在使用过程中会由于各种原因产生病害,为保持桥梁长期运营的安全性,必须对危旧桥梁进行加固改造。文章对新沙立交桥的检测、设计复核、加固方案设计及维修施工进行了全面介绍。实际工程结果表明,旧桥加固改造必须以检测资料为基础,进行必要的结构计算,准确分析桥梁的病害原因,提出科学的改造加固措施,力求达到技术可行、经济合理的目的。Distresses and damage will develop in bridges because of various reasons during the operation of the bridges. To ensure the long-term safe operation of bridges, bridges in danger must be reinforced and rehabilitated. The paper gives a detailed description of the testing, verification of designs, design of reinforcement schemes and repair of Xingsha Overpass. The result of the reinforcement and rehabilitation showed that reinforcement and rehabilitation of old bridges must be based on the testing data to make necessary structural designs, exact analysis of the causes of the damage and distresses to the bridges and proposition of scientific measures for reinforcement of old bridges so as to make such projects technically feasible and economically rational.
