摘要: 通过结构计算软件Midas/Civil分析了不同跨径的空腹式石拱桥在控制截面的永久性下挠变形极限值,并在此 基础上得出了25—65 m跨径的空腹式石拱桥的永久性变形容许下挠值计算公式,可为基层技术工程人员有效方便 地评估桥梁的安全程度起到一定的借鉴作用.

关键词: 石拱桥, 永久性变形, 限值, 有限元分析

Abstract: The ultimate value of permanent lower deflection deformation was analyzed under the control section of diferent span spandrel—braced arch bridges by the structure calculation software Midas/Civil,and the permanent deformation allow— anCe calculation formula of lower deflection to spandrel-braced arch bridges of 25 m to 65 m span length was gained based on this foundation,which would facilitate basic engineers to assess bridge safety rate efectively and convenientely.

Key words: stone arch bridge, permanent deformation, ultimate value, finite element analysis
