石垭子水电站河谷狭窄，单宽流量大，坝后不远处为规模较大的堆积滑坡体，受地形地质条件和工程建设条件限制，工程只能采用挑流消能，而常规挑流消能工雾化水流将会影响坝后左岸堆积体的稳定。通过泄洪消能工体型设计与模型试验研究，提出一种新型的泄洪消能工---半圆锥挑坎双缝消能工。研究结果表明，该消能工能较好的解决下游消能与减小雾化问题，自身结构抗空蚀破坏性能也比较好。

Shiyazi Hydropower Station is characterized by narrow vally and large unit discharge , and a relatively large sliding mass is developed not far from the dam toe .Affected by topographical and geological conditions and restricted by construction conditions ,ski-jump energy dissipation is the only pattern to be adopted ,but the atomized water formed by conventional ski-jump energy dissipation structure will affect the stability of the downstream sliding mass on the left bank . By carrying out the shape design of energy dissipation structure and hydraulic model tests ,a new type energy dissipation structure named semi-cone-shaped ski-jump energy dissipation structure with double joints is proposed .The test results show that this kind of energy dissipation structure can achieve the better effects of energy dissipation ,atomization reduc-tion and cavitation resistance .
