摘要

Stonecutters Bridge in Hong Kong is a cable-stayed bridge having a colossal central span of 1018 m. The dynamic action of gusty wind on the bridge therefore needs careful consideration. In order to obtain a realistic estimate of the wind turbulence characteristics, Highways Department of Hong Kong Special Administrative Region (HKSAR) erected a 50 m high meteorological mast near Stonecutters Bridge and commissioned wind tunnel experiments employing a 1/1500, scale terrain model. Part I of this paper has focused the discussion on the study of mean wind and turbulence intensities. In this Part II of the paper, the other turbulence characteristics including wind power spectra, integral length scales and wind coherences will be discussed.
