摘　　要：通过风洞试验对村镇地区常见的带有硬山搁檩的低矮房屋外墙面风压规律进行研究.讨论了房屋在完全封闭、门窗洞口打开的情况下,风对建筑风荷载的影响及平均风压系数分布规律,由此对比开洞与否对墙体的影响.结果表明,开洞后对房屋正立面和背立面的平均风压系数有明显影响,而对左立面和右立面基本无影响.Based on Wind Tunnel Test,the wind pressure distributions were studied with pressure measurement on wall of low-rise building models in this paper.Two aspects were are respectively discussed: the distribution characteristics of mean pressure coefficient on outside walls of the houses completely closed and the house opened doors and windows,which explaining whether opening the hole or not will do for the house.A detailed analysis of the experimental results shows that there are obvious influences on the front wall and the back wall,and there are no obvious influences on the two flanks of walls,when the houses have holes on the front wall.
