摘　　要：简要阐述了江河含大量泥沙时对渡河工程保障所带来的若干影响，重点分析了泥沙含量与流体的密度、运动粘性系数之间的关系，并用粘性流体理论总结了浮桥的摩擦阻力变化规律，得出泥沙含量大对浮桥阻力的影响不容忽视的结论。Several influences on river-crossing engineering support due to large amount of sediment in the river are discussed. The relationships among sediment concentration, fluid density and kinematic viscosity coefficient are analyzed. The viscous fluid theory is adopted to conclude the changing rules of frictional resistance of the floating bridge. The conclusion is that the influence of sediment on the resistance of floating bridge cannot be ignored.
