三溪口船闸设计水力指标较高，闸室为非标准闸室，输水系统布置受限制因素较多，采用集中输水系统的难度较大。分析了不同消能方式的特点，提出了适合该船闸的格栅帷墙消能室与消力池相结合的消能布置形式，计算了输水系统各部位的尺寸及具体布置；通过1∶20的物理模型试验研究，得到了输水水力特性、闸室流速分布、闸室船舶停泊条件、廊道压力特性以及进出水口水流条件，并提出了相关改善措施，确定了充、泄水阀门开启方式、闸室镇静段长度及下闸首消能室内的挑流坎尺寸。提出的输水系统布置及消能工形式较好地适应了三溪口船闸的工程特点，解决了相关输水系统布置难题，试验成果满足规范及设计要求。

The hydraulic indexes of Sanxikou shiplock are high and the lock chamber is nonstand. At the same time, the layout of filling and emptying system of Sanxikou shiplock is affected by many limiting factors. Therefore, it is difficult to design its end filling and emptying system. The characteristics of different energy dissipating modes are analysed in this paper. And energy dissipating mode that combines grid stilling chamber with stilling basin is put forward and dimensions of the filling and emptying system are calculated. The hydraulic characteristics during lock filling and emptying, velocity distribution characteristics and mooring conditions of ship in lock chamber, pressure characteristics in culverts, and flow conditions at inlet or outlet are all studied and relevant improvement measures are presented through physical model experiment(scale 1∶20). Furthermore,the valve opening modes, length of stilling lock section and dimensions of baffle sill in stilling chamber at downstream lock head are proposed. The energy dissipating type is very suitable for Sanxikou shiplock and many technical problems about layout of filling and emptying system have been solved. The experiment results accord with requirements of criterion and design.
