为了分析大炸高条件下聚能射流对钢筋混凝土的侵彻能力,在考虑了钢筋混凝土靶板强度和射流断裂对侵彻过程影响的前提下,基于准定常侵彻理论,得到了射流侵彻钢筋混凝土深度的计算方法。通过射流侵彻钢筋混凝土试验,得到了不同炸高下的侵彻深度,与理论计算结果进行对比,二者吻合较好,验证了侵彻深度计算方法的正确性。

In order to analyze the penetration ability of energy cumulative jet into reinforced concrete under the condition of big explosion height, considering the influence of the strength of the reinforced concrete target and jet fracture on penetration process, based on the quasi steady penetration theory, the calculation method of penetration depth of energy cumulative jet into reinforced concrete was obtained. The penetration depths of different height of burst were obtained through the penetration test of energy cumulative jet into reinforced concrete. The comparison between the test results and the theoretical results shows that they are in good agreement with each other, which verifies the correctness of the calculation method of penetration depth.
