摘　　要：桥梁在交通运输中起着十分重要的作用。随着使用年限的增长,环境的侵蚀和车辆荷载的增加使得按期对服役桥梁的安全状况进行评价十分必要。本研究提出使用灰色关联度改进TOPSIS的方法进行桥梁耐久性的评价,利用熵权法确定指标权重,综合灰色关联度和欧氏距离计算出相对贴近度并排序来判断评价对象的优劣。通过对工程实例的评价分析和比较,初步验证了灰色关联度改进TOPSIS法的合理性、科学性。Bridges play a very important role in transportation.As the growth of the use fixed number of year,the environment of the erosion and the increase of vehicle load on schedule to evaluate service safety status of Bridges is very necessary.In this paper,using the grey correlation method of improved TOPSIS method to evaluate the durability of Bridges.Entropy weight method is used to determine the index weight,comprehensive grey correlation and Euclidean distance to calculate the relative post progress judge the object can be evaluated and sorted.Through analyzing engineering examples of evaluation and comparison,the rationality and scientificalness of the grey correlation degree improved TOPSIS method were preliminary verified in the paper.
