摘　　要：为了研究浑水体流动时对结构物的作用,根据粘性流体的流动和变形特征,即剪切应力和剪切应变率之间的关系,探究非牛顿流体流动时对结构物造成的作用力。并根据试验测量值推出的拖曳力系数与依据理论计算出的拖曳力系数值进行比较和分析。结果可供类似研究参考。To investigate the forces acting on spherical structures when sediment-laden turbid water flows,this study explores the effects of non-Newtonian fluid flow on structures based on the relationship between shear stress and shear strain rate,which are characteristics of viscous fluid flow and deformation.The drag coefficient derived from experimental measurements is compared and analyzed with the theoretically calculated drag coefficient.The research results can serve as a reference for similar studies.
