| 摘 要： | 利用旋转圆盘空蚀试验装置，通过在拟定水流条件下对不同配合比混凝土材料的抗空蚀试验，测定并分析了该类蚀材的抗空蚀行为。结果表明，水工混凝土在空蚀荷载的交变应力应变和单向应力应变作用下，其空蚀特征参数（如失重率、麻点率、表面裂缝、潜伏时间等）与疲劳特性指标（如断裂韧性、弹模、强度、硬度等）具有良好的相关关系。

| Abstract: | The experiment on cavitation damage resistance of portland cement concretein the rotating circular installation, when the flow velocity is about 50 m/s the cavitation erosion features of different mixed concrete are determined. Authors have analyzed these results and testified that the cavitation features (such as lose weight, cavitation pitting, surfacecrack, continued time etc) have good relation with the fatigue behaviors (such as fracturetoughness, elastic modulus, strength and penetrator diamond hardness). |
