摘　　要：首先介绍了空蚀破坏的原理以及发生空蚀破坏的条件,并分析了龙抬头式泄洪洞发生空蚀破坏的原因和易发生空蚀破坏的部位。最后,结合工程实例的实验结果,说明了发生空蚀破坏的主要原因是不平整度以及体型的不合理。At first, the theory and the happening conditions of cavitation damage are presented, at the same time, the reasons of cavitation damage and the position where the cavitation damage usually takes place are analyzed in tunnel spillways. Finally, the main reasons which are the surface irregularities and the reasonability of construction shape are shown by the experiment results of engineering example.
