中承式肋拱桥受力性能试验研究
|
摘要
随着公路事业的蓬勃发展，公路桥梁建设突飞猛进，日新月异。在诸多结构型式的桥梁中，拱桥是我国公路上使用很广泛的一种桥梁体系。拱桥不仅可以利钢、钢筋混凝土等材料来修建，而且还可以根据拱的受力特点，充分利用抗压性能较好而抗拉性能较差的圬工材料来修建。拱桥具有跨越能力大；能充分做到就地取材；耐久性强；养护维修费用少；外型美观；构造简单等优点。在今后的桥梁建设中，拱桥仍将是我国公路桥梁的一种主要型式之一。
目前，拱桥桥型也越来越倾向于轻型、大跨，而中承式肋拱拱桥是一种比较常见的拱桥类型，本文介绍了中承式钢筋混凝土拱桥的构造以及其恒载、活载和吊杆的内力计算等内容，重点以内蒙古赤峰市阴河大桥的静、动载试验为例，分析了桥跨结构的技术状况、承载能力和动力特性，评价了桥梁的正常使用性能，为此类桥型的设计和施工积累了经验。
With the flourish development of the highway, the construction of the bridge develop very fast .In the lots type of bridges ,the arch bridge is a very common system in our country. The arch bridge has a lot of virtues : it's span could be so large, the materials of the arch bridge can be got very easily ,the shape of this type is very beautiful and the structure is simple. In the future ,the arch bridge will be also very important type .
Nowadays the arch bridge type is changing to light and large span .In lots of large span arch bridges ,the middle supporting arch bridge is a very familiar type .In this paper ,the structure and force calculation of the middle supporting arch bridge are introduced .The more important content is the static and dynamic experiment of the Yinhe bridge ,which locates in NeiMeng Province.With this experiment ,we analysed the bridge's technique status .bearing capacity and dynamic capability .All of these would provide many experiences for this bridge type in design and construction .
