云龙水库泄洪洞空蚀及体形优化研究

Research on cavitation damage and figure optimization for spillway tunnel of Yunlong Reservoir

结合云龙水库工程实例,综合分析了龙抬头式泄洪洞产生空蚀的原因及该工程产生空蚀的可能性;在满足工程要求的条件下,提出了龙抬头体形修改建议,通过模型试验验证了修改的合理性.

Combined with a practical engineering example, Yunlong Reservoir, both the reason causing cavitation damage for spillway tunnel and the possibility producing cavitation damage for the project are analyzed comprehensively. The proposal concerning amending the figure of spillway tunnel is put forward so as to satisfy the conditions of the practical project. Through the model test, the rationality has been proved.
