摘　　要：羽翼袋沙障是一种新型沙障,可增大风沙阻力,减弱风速,达到底袋固沙、羽翼消风的作用,提高了防风固沙效果。通过与传统沙袋沙障对气流速度、风沙流结构及相对阻沙能力的影响比较,分析了羽翼袋沙障的防风固沙效果,为防沙治沙筛选新材料提供依据。研究结果表明:3种风速下,羽翼袋沙障有效防护范围较沙袋沙障增大3.99~7.50倍,减弱风速效能提高10.50%~21.23%;沙袋沙障各点位输沙量均大于羽翼袋沙障,各高度阻沙能力系数反之,羽翼袋沙障相对阻沙能力较沙袋沙障增加1.19~1.36倍。As a new type of sand barrier,wingbag sand barrier can improve the wind and sand fixation effect with increasing the wind resistance and weakening the wind speed in order to achieve the effect of sand fixation of bottom bag and wind dissipation of wing.Through comparing the influences of traditional sandbag barriers on airflow velocity,wind sand flow structure and relative sand blocking ability,the wind and sand prevention effects of wingbag sand barrier were analyzed in order to provide the basis for screening new materials of sand prevention and control.The results showed that under three kinds of wind speed,the effective protection range of the wingbag sand barrier was increased by 3.99-7.50 times compared to traditional sand bag sand barriers,and the efficiency of reducing wind speed was improved by 10.50%-21.23%.The sand transporting quantity of traditional sandbag at each point was greater than that of wingbag sand barrier,the sand resistance capacity coefficient at different heights was inversely,and the relative sand resistance ability of wingbag sand barrier was increased by 1.19-1.36 times.
