Abstract：Flow around the roof can cause the complex movement of the snow on the long-span roof, which results in uneven distribution of the snow. In recent years, the collapse of the long-span roof caused by uneven distribution of snow has been common, so it is very important to predict the distribution of snow on the long-span roof correctly. In this paper, based on the Mixture model and turbulent model, the numerical simulation of snow drifting has been performed on typical form of long-span roofs. The characteristics of snow distribution are discussed considering some parameters such as wind direction and rise-span ratio. Then the simulation result is compared with Chinese Code for the flat roof and cylinder roof.
