around a long-span bridge site in mountainous terrain in western China. Anemometers
were installed over the height of the bridge site to measure both instantaneous
wind speed and direction as well as their means. Turbulence intensity results
showed that, the mean wind speed at the site presented complex variations over
its height,the turbulence intensity at height of 10 m above the arch springing
exceeded 40% and at 90 m it was still as high as 15%. The sites
wind speed profile did not follow either logarithmic or exponential models.
The measured horizontal turbulent wind speed spectrum was closer to an Irwin
spectrum, but differed from the Simiu spectrum: vertical turbulent wind speed
spectra differed from the Panofsky spectrum.]]>Zhang, Y., Z.T. Hu and J.X. Liu,200830154155Zhang, L.L., H. Liu, Z.Y. Yang, J.M. Zhang and W.F.
