摘　　要：刘家峡水库联合调度以后,溢洪道堰顶露出的机会很少,溢洪道工作闸门及门槽失去了正常检修的条件。为确保溢洪道工作闸门正常运行,必须增设检修闸门以便对溢洪道工作闸门系统进行全面维护检修。就增设检修闸门的技术方案进行了认真研究,并对浮体检修门的封堵和止水进行了详细论证。After the joint regulation of Liujiaxia reservoir,the top of spillway scarcely exposed,and there is no way to repair the service gate and slot regularly.In order to ensure the normal operation of the spillway service gate,it is necessary to add emergency gate so as to maintain and repair the service gate system of the spillway completely.The paper carefully studies the technical option concerning the addition of emergency gate,and justifies the blocking and water sealing of the floating emergency gate in detail.
