摘　　要：体型不合理和混凝土表面局部不平整是泄水建筑物表面发生空蚀破坏的主要原因。分析了泄水建筑物空蚀破坏的产生条件和特点 ,提出了防止和减少空蚀的具体措施。Imappropriate type of build and partially uneven surface are the main causes of cavitation damage on the surface of sluicing structure. This paper discusses the conditions and characteristics of cavitation damage. Preventing and eliminating methods including making the build type of the sluicing border rational, improving the evenness of sluicing surface, mixing air to eliminate erosion and using cavitation resisting facing materials etc are introduced.
