摘　　要：应用计算流体动力学软件平台FLUENT,采用气固两相流理论,对自定义屋面在不同风向、风速作用下,模拟其对屋面在持续性降雪过程中积雪的不均匀分布情况的影响,通过对积雪分布情况的分析,找出风致积雪过程中风向、风速对其的最不利影响,为结构静力设计和雪荷载规范的完善提供理论依据。Applying CFD software platform FLUENT,using gas-solid two-phase flow theory,the paper simulates the impacts of uneven roof snow distribution in continuous snowing process under the action of various wind direction and wind speeds of self-defined roof.Through analyzing the snow distribution conditions,it finds out the most unfavorable impact of wind direction and wind speed in wind-inducing snow process,which has provided theoretical basis for perfecting structural static design and snow loading design standards.
