Calculation and analysis of the design benchmark wind speed of the Xinjiang Saiwu Diego Bridge

In order to ensure the wind safety of the Saiwu Diegor Bridge, which has an extremely important position, the basic wind speed data of the Fuyun County Meteorological Station in the bridge site area were used to analyze the basic characteristics of the average wind speed, maximum wind speed, extreme wind speed over the years, and the average wind speed and wind direction of each month. The maximum wind speed sequence of the weather station was established year by year, and the design basic wind speed at different recurrence periods of the bridge was calculated by using extreme value I. type, Pearson type III. and different specifications. At the same time, considering the different types of land surface in the Karasuk Reservoir where the bridge is located, the design benchmark wind speed at the bridge deck is deduced, which provides an accurate basis for wind tunnel test and wind load calculation during flutter, jitter analysis and structural analysis of the bridge.
