通过单体水工模型试验，研究河口村水库高流速泄洪洞的掺气减蚀措施，优化泄洪洞体型。结果表明：1＃泄洪洞弧门后突扩突跌掺气体型合理，能形成稳定空腔，达到掺气减蚀目的；2＃泄洪洞龙抬头末端突扩突跌掺气效果好，从洞身水面以上取气能满足掺气需求；2＃泄洪洞鼻坎顶高程决定了其运行范围及方式，可低于下游最高洪水位。

Relying on single hydraulic model tests,it researched the high velocity spillway tunnels aeration for mitigating cavitation and optimized the spillway tunnels size. Results and Conclusions:The type of sudden fall and sudden enlargement behind the radial gate of the No. 1 spillway tun-nel is reasonable,the stability cavity under the flow can be formed,the performances of aeration and corrosion reduction are better;The type of sudden fall and sudden enlargement on the end of the No. 2 tunnel spillway is reasonable,the performances of aeration and corrosion reduction are better;The operation mode of the No. 2 spillway tunnel depends on the elevation of the bucket lip in the export structure and the elevation of the bucket lip can be lower than the maximum flood level of the downstream.
