基于改造底缘的水电站事故平板闸门 启闭力优化试验研究

通过加拿大Mica水电站进水口事故闸门水工模型试验，研究论证了该电站加大流量情况下事故闸门的闭门持住力特性。针对闸门启闭机设计容量不足的问题，给出了5种闸门底缘改造方案，分析比较了不同方案对降低闸门持住力的效果，提出了可行的工程方案措施，为闸门的设计及安全运行提供了参考依据。

Experimental study on optimization of hoisting force of emergency plate gate for hydropower station based on improvement of its bottom edge

On the basis of the hydraulic model test of the intake emergency plate gate for Mica Hydropower Station in Canada, the characteristics of the closing-holding force of the gate when flow increasing are studied and demonstrated herein; from which five schemes of improvement of the bottom edge of the gate are proposed in allusion to the problem of the insufficient design capacity of the gate hoist. Simultaneously, the effects of the various schemes on reducing the holding force of the gate are comparatively analyzed, and then the relevant feasible engineering schemes and measures are put forward for providing references for the design and safe operation of the gate.
