| 中文摘要: |
| 架设在峡谷上的大跨度桥梁，由于桥位处地形复杂，离谷底较高，设计基准风速一般无法通过抗风规范查得，需要进行专门的分析或测试。针对坝陵河大桥的设计基准风速问题，分别通过附近气象台站的数据和专门架设的观测塔的观测数据，通过分析得到了桥位处的设计基准风速。对类似地貌大桥建设设计基准风速的取得具有一定的参考意义。 |
| 英文摘要: |
| When a large span bridge is constructed over a barranco, the design standard wind speed usually cannot be obtained directly from wind resist design specification because of the complex topography and the long distance from the valley bottom. So special analysis and tests are needed. In this paper, the design standard wind speed of Baling River Bridge is obtained from the analysis of the data observed by weather station nearby and observing tower especially built for this problem, which provides reference for bridges with similar landforms. |
