Controlling crack of hyperbolic arch dam with a height of 305 m in Jinping hydropower station is an important problem. To improve the anti-cracking ability and reduce cracking risk of hydraulic concrete, polyvinyl alcohol (PVA) fiber and polypropylene thick fiber were used in hydraulic concrete using four gradations of aggregates. Indoor and productive tests were carried through to comparatively analyze workability, physical and mechanical properties and anti-cracking ability. Workability of fiber reinforced concrete was improved to be in favor of construction. When two kinds of fiber were used in concrete, the anti-cracking ability was greatly enhanced with lower elastic modulus-to-strength ratio and lager ultimate tensile strain. Concrete using PVA fiber had better anti-cracking ability than that of concrete using polypropylene thick fiber. PVA fiber reinforced concrete was applied in Jinping hydropower station. It is proved that PVA fiber reinforced concrete has good properties reaching design requirements of workability, compressive strength, ultimate tensile strain, frost resistance, permeability resistance.
