摘　　要：贵州黔西电厂干煤棚跨度为180m,为确定干煤棚设计风载以及干煤棚纵向长度对风载分布的影响,在北京大学环境与湍流研究国家重点试验室分别进行了90M和181.5M的风洞模拟试验,经过数据分析,其结果可以供设计同类型工程或者干煤棚扩建时参考。The dry-coal-shed in Power Plant always be arched constructiorL In order to acertain its design wind load and the influence of its length on the wind load distribution, basing on the dry - coal - shed in Qianxi Power Plant, a simulation experiment was taken in state key laboratory for turbulence and complex systems research, Peking University, with the length at 90m and 180m separately. By data anlysis, the experiment result can be used for dry coal shed expanding or similar projects.
