Abstract: The experimental investigation on the Rebuilding Project of Peacock Art Square in Kunming Expo Garden is presented in this paper. During the experiment, the local wind field is simulated, in the same time, the mean wind pressures and the RMS wind pressures on the roofs of audience area and platform, as well as the frequency of vortex sledding in the downstream of the audience area are measured. Experimental results show that, because of the influence of vortex sledding in the downstream of the cliff, the instantaneous wind pressures on the roofs are very high, the wind pressure distributions on the roofs of the audience area vary obviously in main wind direction, and the RMS wind pressures are very strong. The mean wind pressures on the roofs of platform are small, but its instantaneous wind pressures are very high.
