水工混凝土材料抗裂性(抗裂指数)与水工混凝土结构抗裂性(抗裂安全系数)是两个不同的概念，不能混淆。

The crack-resistance of hydraulic concrete material (crack-resistance index) and hydraulic concrete structure (safety factor of crack-resistance) are two different concepts, which can not be obscured.

借助弯曲荷载-挠度全曲线，分析了纤维掺量和类型对韧性指数和初裂荷载的影响。结果表明，钢纤维混凝土的抗弯初裂强度、极限强度和弯曲韧性均随纤维掺量的增大而提高。

Through the load-deflection curves of SFRC, the effects of fiber kinds and fiber content on the first-crack strength and the flexural toughness of SFRC were contrasted with those of concrete.
