摘　　要：以G0711天山北坡段为研究对象,通过线路调查,查明沿线山前冲洪积区、乌鲁木齐河阶地区、剥蚀构造中山区、山间断陷盆地积雪段占比不同,山前冲洪积区及山间断陷盆地积雪较多,并分析其形成原因;进行现场试验测量积雪密度,经测量积雪密度较小,属于新雪;对风吹雪地段采用Fluent软件进行数值模拟,分析风吹雪灾害最可能发育的具体地带,并提出填方路基坡比设置为1∶4及背风半路堑路基两侧设置积雪平台的建议,为防治工程提供依据;提出防治建议,采取路基设计及工程防治措施(防雪栅栏、储雪沟、防雪林)联合实施。This paper takes the north slope section of Tianshan G0711 as the research object. Through investigating the line, it is found that the proportions of the snow cover section are different in the piedmont alluvial proluvial area, Urumqi River terrace area, middle mountain area of denudation structure and intermountain fault basin, and there is more snow cover in the piedmont alluvial proluvial area and intermountain fault basin. Its formation reasons are analyzed. Field test is carried out to measure the snow density. The measurement results show that the snow density is small and belonged to fresh snow. Fluent software is used to simulate and analyze the specific zone where snowdrift disaster is most likely to happen in the study area. In order to provide basis for prevention and control engineering, it is proposed that the slope ratio in fill subgrade is set to 1∶4 and the snow platform is set on both sides of leeward half cut. The prevention and control proposals that roadbed design and engineering prevention measures(snow fence, snow storage ditch, snow forest) are jointly implemented are put forward.
