中文摘要：

这研究在河岸斜坡经分解上并且试验性地在非连贯的沉积粒子的起始的运动上调查地面水注射的影响。由在力量分析包括水力的坡度，批评条件被导出说明渗出物流动的效果，证明水力的坡度和河岸斜坡正在管理的渗出物在在一条河岸上修改沉积的早期的运动的参数倾斜。试验性的调查为各种各样的河岸斜坡和注射的水力的坡度在开隧道的斜槽被执行，证明批评砍有减少的河岸斜坡和钳子的压力增加，当注射减少批评价值时。所有试验性的数据在注射的情况中与批评条件的理论导出的表达式同意很好。

英文摘要：

This study investigates the influence of ground water injection on the initial movement of non-cohesive sediment particles on a riverbank slope analytically and experimentally. By including the hydraulic gradient in the force analysis, the critical condition was derived to account for the effect of seepage flow, showing that the seepage hydraulic gradient and the riverbank slope are governing parameters in modifying the incipient motion of sediments on a riverbank slope. Experimental investigations were performed in an open-channel flume for various riverbank slopes and hydraulic gradients of injection, showing that the critical shear stress increases with decreasing riverbank slopes and vise-versa, while injection reduces the critical value. All experimental data agree well with the theoretical derived expression of the critical condition in the case of injection.
