中文摘要：

分别采用激光连续式路面平整度仪与水准仪对福鼎桐山大桥的桥面平整度进行了测量,采用最大熵谱法进行桥面平整度的频谱分析,获知了使用激光连续式路面平整度仪测量的优势。对福建省内多座钢管混凝土拱桥的桥面平整度进行了采集和分析,进一步验证了桥面平整度功率谱法与国际平整度指数法的关系方程式的正确性;从主梁型式、主拱跨径、使用年数等方面对钢管混凝土拱桥桥面平整度进行了分析。发现桥面平整度指数随使用年数的递增呈指数形式增大,据此提出了桥面状况与使用年数的关系式,可简便地进行钢管混凝土拱桥桥面状况的预估。

英文摘要：

The deck roughness of Tongshan Bridge in Fuding was measured by using leveler and laser continuous pavement profilometer respectively.Maximum entropy method（MEM）for the spectrum analysis of deck roughness was adopted,and the advantage of laser continuous pavement profilometer was obtained.The deck roughnesses of several concrete-filled steel tubular（CFST）arch bridges were collected and analyzed,and the presented relationship between two main methods,which are power spectral density（PSD）method and international roughness index（IRI）method,was configured.The deck roughnesses were evaluated from main beam type,main span of arch and service years.It is found that IRI value with exponential form increases following service years.Therefore,the relationship between deck roughness and service years is presented,which can simply predict the deck condition of CFST arch bridge.2 tabs,9 figs,14 refs.
