Abstract: Based on considering the effect of bottom shear stress on the spiral flow in bend reach, this paper develops the expressions of velocity distribution transverse slope and shear stress. The relationship between circulation and cross-section formulation is also presented, and the comparisons made here show that the theoretical results agree with river and experiment data quite well.

摘要： 本文在研究底部切力对弯道环流的影响的基础上,推导了环流流速分布,横比降及底部切力等公式,并给出了弯道环流与横断面形态的关系式。用天然河道和试验资料验证,表明这些公式与实测资料比较符合。
