空腹式悬链线无铰板拱桥可靠性评定研究

Study on Reliability Assessment of Spandrel Braced Strandless Arch Bridge of Catenary Suspension Construction

随着公路桥梁运营时间增长,其结构出现累积损伤,影响到公路的安全服役。鉴于空腹式悬链线无铰板拱桥受力特性,现以贵州某公路拱桥为例,通过现场检测及数值计算的方法进行可靠性评定,计算结果表明该拱桥符合稳定性要求。

As serving time increases,bridge injuries and damages begin to appear,which causes potential dangers of traffic.Considering the special force system of spandrel braced strandless arch bridge of catenary suspension construction and taking one arch bridge in Guizhou as an example,the bridge reliability is assessed through field testing and numerical calculation in this paper.
