| 摘 要： | 分析润扬长江公路大桥桥位风速观测站与丹徒县气象观测站同步风速风向观测的有关内容,两站的观测值存在良好的正相关性,采用Gumbel分布函数拟合极值频率分布,计算得到大桥的不同重现期基本风速,与根据建筑结构荷载规范推算的结果对比分析,确认计算结果的合理性,完成各高度层上的大桥设计基准风速计算。为确保大桥抗风安全,指导施工提供了可靠的技术指导。

| Abstract: | This paper analyzes the wind speed of Wind Speed Monitor Station at Runyang Bridge and Wind Speed Monitor Station at Weather Station of Dantu.The monitoring data of both stations showed positive correlation. By fitting extremum frequency distribution with Gumbel Distribution Function principal wind uelocitiesin different recurrence period are claculated. The calculated results provide credible technical guide to construction of Runyang Bridge and ensure wind resistance safety. |
