Abstract： Abstract: To realize the effective stochastic wind filed simulation for long span cable-stayed bridge, a fast wavelet method which can simplify the stochastic wind field simulation is set according to its figure characteristics, which can consider the wind on tower, cable and beam synchronously. During simulation, the 1-dimensional multivariable stochastic process is fast calculated according to the multiple resolution characteristics of wavelet and Mallat algorithm；the autocorrelation function matrix is extended to crosscorrelation function matrix by considering the correlation of space point, and the wavelet method is extended to simulate the 1D-nV stochastic process by reference the auto-regression method；the corresponding expressions are formulated. Finally, the validity of the method proposed is proved by compared with the spectral representation method and linear filter method.
