摘　　要：就泸定水电站2号泄洪洞事故闸门的结构设计、启闭机形式及容量的选择、门槽体型及动水闭门特性等问题进行论述。通过技术、经济等多方面综合比较分析,事故闸门采用上游止水、滚子轴承定轮支承、利用加重闭门的平面定轮闸门。该研究成果可供类似工程设计参考。This paper introduces the structural design of emergency gate to 2 spillway tunnel of Luding Hydropower Station, the option of model type and capacity of Hoist, somatotypes of gate slot and characters of dynamic water closed door. Through the comprehensive comparative analysis of technical, economic and other aspects, the emergency gate adopts fixed wheel plane gate which can use upstream to retain water and is sustained by the roller shaft bearing fixed wheel and increase the weight of close gate. The re- sults function as a valuable reference for the design of similar projects.
