钢拱架支撑法施工是拱桥施工中一种常见的施工方法,但是随着拱桥在高速公路等大交通量道路设计中的应用,由于跨度大、桥体宽对拱架设备的一次需求量增大,造成施工成本过高,如分次施工则进度缓慢。为了解决这一矛盾,山东博莱高速公路下佛羊百米箱形拱特大桥施工中首次开发利用了百米柔性钢拱架整体横移技术。文章以该桥的施工为例介绍此项技术的应用,供同类桥梁设计、施工时参考。 However, with the application of arch bridge in the design of large traffic such as expressway, the demand of arch bridge equipment is increased due to the large span and wide bridge width Large, resulting in the construction cost is too high, such as sub-construction is slow. In order to solve this contradiction, the overall traverse technology of the 100-meter flexible steel arch was developed and utilized for the first time in the construction of the box-shaped arch bridge of the Buddha in the Bolai Expressway in Shandong Province. The article takes the construction of the bridge as an example to introduce the application of this technology for the design and construction of similar bridges.
