中文摘要：闸室稳定性、结构强度、闸基渗流稳定等是影响水闸安全的主要因素,在水闸失事原因中,由于渗流破坏引起的事故占比大,因此,水闸的渗流计算的研究具有十分重要的实际意义.文章用改进阻力法计算板桩不同贯入度0％,10％,20％,30％,40％,50％,60％,70％,80％,90％,95％,96％,97％,98％,99％,100％闸底板水平渗透坡降和出口出逸坡降,得出了板桩不同贯入度的防渗规律;在给定闸底板水平和出口容许渗透坡降情况下,得出了板桩最佳贯入度;用AutoBank有限元软件计算板桩最佳贯入度情况下的闸底板水平渗透坡降和出口出逸坡降,并对两种计算方法的结果进行比较分析,得出两种方法的适用性.

外文标题：Influence of sheet pile penetration on seepage stability of sluice in sand-gravel foundation

外文摘要：The stability of sluice chamber,the structure strength,the seepage stability of sluice foundation are the main factors that affect the safety of sluice.In the causes of sluice accidents,the accidents caused by seepage damage account for a large proportion.Therefore,the study of seepage calculation of sluice has very important practical significance.In this paper,the improved resistance method is used to calculate the horizontal seepage slope of sluice floor and the outlet slope of sluice outlet with different penetration degrees of 0％,10％,20％,30％,40％,50％,60％,70％,80％,90％,95％,96％,97％,98％,99％,100％,and the seepage prevention law of different penetration degrees of sheet pile is obtained.In the case of given horizontal seepage slope of sluice floor and allowable seepage slope of outlet,the op-timal penetration degree of sheet pile is obtained.The finite element software AUTOBANK is used to calculate the horizon-tal seepage slope of sluice floor and the outlet slope of sluice outlet with the optimal penetration degree of sheet pile.The results of the two calculation methods are compared and analyzed,and the applicability of the two methods is obtained.
