Abstract: Based on the operation of several domestic chute spillways over the years, the main defects and causes are analyzed. Aiming at the main problems including cavitation, erosion and structural damage caused by poor structural design, concrete construction defects and aging, as well as downstream erosion, flood discharge atomization and et al., countermeasures and precautions are proposed to provide reference for similar projects in design, construction, operation and maintenance.

Key words: chute spillway, operation, defect, scour, erosion, cavitation, atomization, maintenance

摘要： 根据国内多个河岸式溢洪道历年运行情况，统计、分析了运行中常见的主要缺陷和成因。针对结构体型设计、混凝土施工缺陷和老化等原因引起的空蚀、冲蚀和结构破坏，以及下游冲刷、泄洪雾化等方面的主要问题，提出了相应的对策措施，供类似工程在设计、施工及运行维护中借鉴。
