摘要
近年来,随着山区高速公路的飞速发展,很多地方高速公路需跨越深山峡谷,对桥梁的跨度、稳定性、安全性及造价的要求越来越高,斜拉桥、悬索桥、拱桥虽跨度大、结构美观,但造价高,普通连续刚构桥造价低,但跨度小,满足不了山区跨度大的河流峡谷,因此空腹式连续刚构桥越来越多地被使用在山区高速公路上,该桥型具有跨度大、刚度大、挠度小、良好的稳定性和安全性、造型美观、造价低等特点。文章主要以宜来高速鹤峰东段云南庄特大桥为例,研究空腹式连续刚构桥的上、下弦施工工艺及相关支架等施工措施的受力计算,可供类似工程借鉴和参考。
In recent years,with the rapid development of mountain highways,many local highways need to cross deep mountain canyons,and the requirements for span,stability,safety and cost of bridges are higher and higher.The article mainly discusses the east section of Hefeng from Yilai Expressway As an example,the mechanical calculation of the upper and lower chord construction technology and related support of the hollow continuous rigid frame bridge is studied,which can be used for reference in similar projects.
