猴子岩电站非常泄洪洞由导流洞改建而成，非常泄洪洞体型的合理性及抗空化性能的好坏直接关系到该工程能否成功运行。本文通过研究，在常压模型试验的基础上，确定采用有压洞塞式泄洪洞改建方案；并通过减压模型试验，提出了“垂直射流+直弯洞塞+水平洞塞组”的消能模式，确定非常泄洪洞的最终体型。减压模型试验表明，该体型的抗空化性能满足工程要求。这一成果，为导流洞改建泄洪洞的推广应用开辟了新的途径。

Unusual flood-releasing tunnel of Houziyan hydropower station was rebuilt by diversion tunnel.The reasonability of the unusual flood-releasing tunnel shape and the anti-cavitation performance were directly re-lated to successful operation of the project.Through this research ,based on a atmospheric pressure model test , the project determined to use the reconstruction plan of pressure plug flood-releasing tunnel;and proposed the“vertical jet+straight curved hole plugs+horizontal hole plugs groups”energy dissipation mode to determine the final shape of flood-releasing tunnel by decompression model test.Decompression model tests showed that the shape's anti-cavitation performance can meet the engineering requirements.The result opens up new avenues to promote the application for the reconstruction of diversion tunnel into flood-releasing tunnel.
