  • In order to determine snow cover distribution exactly, reduce the snow and wind disasters, the field survey of snow cover distribution of building was carried out. By using the software Fluent, the numerical models of wind-induced snow cover on arched roof were set up considering air-phase relative velocity, air-phase velocity, air-phase relative angular velocity, snow density and other factors to simulate the distribution of wind-induced snow cover on arched roof. By analyzing the data, the main factors affecting the snow cover distribution on the roof were found out, the turbulence model of wind and snow effect was established, and the statistical data of the pressure generated by the snow cover on the arched roof was analyzed in detail, and suggestion of the value of the uneven distribution coefficient of the snow cover on the arched roof was proposed, in order to make up for the situation that the current norms in China have more adequate consideration for the value of the uniform distribution coefficient of snow cover, but inadequate consideration for the value of the uneven distribution coefficient.
