装配式公路钢桥在国家建设中发挥了很大的作用,目前装配式公路钢桥的跨径基本在60m左右,为了提高其跨越能力,设计了70.104m和90.440m两种不同跨径的斜拉装配式公路钢桥。该桥型充分利用了已有的构件(“321”型和200型),且较现有的贝雷式悬索桥施工更为方便,为我国应急抢险救灾,快速克服江河障碍,增加了选择余地。荷载试验证明这种斜拉装配式公路钢桥具有可行性。
The prefabricated highway steel bridge plays a very important role in the national construction. At present, the span of the prefabricated highway steel bridge is about 60m. In order to improve its spanning capability, two kinds of diagonal cross-sections of 70.104m and 90.440m Pull assembled highway steel bridge. The bridge type makes full use of the existing components (“321” type and 200 type) and is more convenient than the existing Beilea suspension bridge construction, which increases the choice for our country’s emergency rescue and disaster relief, rapid elimination of river barriers room. Load tests prove that this type of cable-stayed highway is feasible.
