【摘要】 随着水电站高坝建设的发展，传统的闸门止水形式已无法满足高水头工作闸门的止水要求，科技工作者在不断研究新型、合理、可靠的止水型式。本文结合小浪底水电站工程对高压闸门压紧式止水的另一型式ＮＹⅡ型的水密性能进行试验研究，试验结果满足工程要求，是一种封水效果较好的止水形式。更多还原

【Abstract】 Along with the development of high dam construction in hydropower project, the traditionaltypes of gate seal can not meet the needs of high pressure gate. In this paper, combining with Xi-aolangdi hydropower project, another new type of seal (compressible type NY Ⅱ) was presented.Based on laboratory test and study,the watertight properties have proved effective.更多还原
