In order to learn the wind environment and the parameters of the wind environment at the sea-crossing bridge in Guangxi, the characteristics of the mean wind(mean wind velocity and directions, maximum wind velocity and instantaneous maximum wind velocity) and the fluctuation wind(the wind attack angel, turbulence versus, turbulence integral scale and turbulence power spectrum) are presented at site of the bridge, on the basis of the field measurements of the near-ground wind environment using the observatio...
