摘　　要：黄河下游挖河疏浚固堤启动工程在黄河口断流河段采用了机械清淤方法 ,施工期间由于天气干旱 ,汽车跑动和风力作用等 ,对施工区周围环境造成一定污染。本文采用实测资料和理论分析相结合的方法对道路风沙起动和扬起输移的范围进行了研究 ,并提出防治措施 ,为今后大规模挖河疏浚提供参考。The mechanization of dredging has been adopted in the channel excavation dredging and dykes reinforcing work in the reach of the Yellow River mouth. Owing to arid climate, car running and wind forces etc., wind-sand pollution influenced the surrounding environment on a certain extent. This paper studied the incipient motion and transport of wind-sand on roads by means of measured data and theoretical analysis, proposed some harnessing measures and provided some experiences for a large scale of channel excavation dredging in the future.
