| 摘 要： | 本文针对实测的桥面平整度的特点，提出一种桥面平整度谱分析的分析方法－极大熵法。对在２０座桥上实测的７４条不同结构类型的桥面平整度特性曲线，利用极大熵法进行了谱分析，提出了用于分析行进车辆荷载作用下桥梁动力响应的桥面平整度的功率谱密度表达式。

| Abstract: | This paper, according to the characteristics of the road surface roughness on highway bridges, pressents a method of spectral analysis of surface roughness on highway bridges, i.e, maximum entropy method(MEM). Seventy-four road surface roughness lines measured on 20 bridges ale calculated by this method. The appropriate power spectral density(PSD) of the road surface roughness on bridges,which is used to analysis the dynamic response of bridges under moving vehicles,is presented. |
