摘　　要：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(The Army Corps of Engineers)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。The penetration resistances of ordinary concrete and steel fiber reinforced concrete mixed with high hardness aggregate were evaluated by virtue of a semi-empirical formula,based on rather wide penetrating experiences.The application area and limitations of the formula were analyzed.A revisional ACE formula was put forward by introducing the hardness of aggregate and the toughness index of steel fiber reinforced concrete.The calculation results by using the revisional formula are in good agreement with the test results,which verifies the rationality of the revisional ACE formula of concrete.
