应用较为广泛的侵彻经验、半经验公式对普通混凝土和高硬度钢纤维混凝土抗侵彻性能进行了评估，分析了公式的应用范围与局限性，为此将骨料硬度和钢纤维混凝土韧度引入到侵彻深度的计算公式，在试验基础上提出了修正ACE公式。修正公式计算结果与实际测定结果符合良好，证明了该公式的合理性。
Abstract
Penetration resistance of ordinary concrete and the steel fiber reinforced concrete mixed with high hardness aggregate was evaluated by using more widely experience, the semi-empirical formula, and the application range and limitations of the formulas were analyzed. The revisional ACE formula is put forward by introducing the hardness of aggregate and toughness index of steel fiber reinforced concrete. Calculation result with revisional formula was in good agreement with test result, which verified the rationality of the revisional ACE formula of concrete.
