| 摘 要： | 针对目前城市中存在的道路车辆拥挤、行人过街难,以及在道路拓宽过程中对原有设施浪费等问题,提出一种新型天桥形式——跨度可伸长式人行过街天桥.通过建立受力模型,进行分析计算,结果表明实现天桥跨度的伸长是可行的.对类似工程的研究可提供一定的借鉴作用. |
| 关 键 词： | 人行天桥 主梁 钢结构 跨度 可伸长性 |

| Abstract: | Aiming at the problems that it is difficult for the passersby to cross crowded roads in cities,and the wastes of primary establishment in the course of widen old roads,the paper puts forward an idea of building a new pedestrian bridge whose span could elongate.And then the academic analysis of it has been made.By assuming a model which bears a certain force and analyzing of the model,the result shows that the format of the pedestrian bridge is reasonable. This paper could offer some reference value to similar engineering. |
