消能设施损坏的主要原因有:①水流的气蚀作用;②高速水流情况下表面、底层和规律性漩涡中建筑垃圾对混凝土的磨损;③水流的动力及振动作用;④结构缺陷。对消能设施的运行条件和损坏原因进行分析后可以得出结论,多数损坏是由互为影响的某些因素彼此作用而产生的。
The main causes of damage to energy-dissipating facilities are as follows: (1) the cavitation effect of water flow; (2) the wear of concrete on the surface, bottom and regular eddies under high-speed water flow; (3) the dynamic and vibration effects of water flow; (4) structural defects. An analysis of the operating conditions of the energy-dissipating facility and the causes of the damage can lead to the conclusion that most damage is caused by the interaction of certain factors that affect each other.
