摘　　要：随着水利工程建设的不断完善,小型水闸的数量越来越多。水闸上游连接段处于重要的部位,其结构型式选择是否合理至关重要。通过对常见的几种型式进行优缺点分析,提出各自的最佳适用条件;同时还创新性地提出"整体导流式铺盖"的概念,并重点对其进行了论述和分析。整体导流式铺盖与其他几种常见的布置型式相比具有整体稳定性好、结构内力小、防渗性能好、缩短水闸总长度、投资少等诸多优点,非常适用于土基上的小型水闸。With the continuous improvement of water conservancy project construction,the number of small sluice is increasing. The upsteam connection section of sluice is an important part,whose structure type is very important. The advantages and disadvantages of several common types are analyzed,and the best applicable conditions are proposed in this paper. At the same time,the concept of Integral Diversion Bedding is put forward innovatively,and it is discussed and analyzed emphatically. Compared with other common layout types,Integral Diversion Bedding has the advantages of better overall stability,less internal force,better anti-seepage performance,shorter total length of the sluice and less investment,which is very suitable for small sluice on soil foundation.
