摘　　要：为了研究聚能射流对土壤/混凝土复合目标的侵彻效应,分析土壤/混凝土复合目标在聚能射流侵彻下的响应特性,通过考虑聚能射流侵彻下塑性波在靶板中的传播和衰减,以及在土壤/混凝土界面的反射和透射,分析了反射波和透射波作用下射流对土壤和混凝土的侵彻过程,研究土壤/混凝土复合目标界面效应对聚能射流侵彻的影响,建立了聚能射流侵彻土壤/混凝土复合目标的理论模型。对聚能射流侵彻单一混凝土靶和土壤/混凝土复合靶进行对比试验发现,由于反射波和透射波的影响,聚能射流对土壤/混凝土复合靶的侵彻深度反而低于对单一混凝土靶的侵彻深度。在反射波和透射波的作用下射流的侵彻速度下降,导致了对土壤/混凝土复合靶侵彻深度的降低,试验结果与理论分析一致。In order to study penetration capability of shaped charge jet penetrating into a soil / concrete target,the response characteristics of the soil / concrete target under shaped charge jet penetration were analyzed. Considering propagation and attenuation of plastic wave and its reflection and transmission on soil / concrete interface,a theoretic model of shaped charge jet penetrating into the soil / concrete target was built by analyzing influence of reflection wave and transmission wave on the jet penetrating into the soil and concrete target. The comparative tests of jet penetrating into a concrete target and a soil / concrete target,respectively were performed. It was shown that the jet penetration depth into the soil / concrete target is lower than that into the concrete target owing to influences of reflecting wave and transmission one;the action of reflection wave and transmission wave,the penetration velocity decreases to cause the reduction of the jet penetration depth into the soil / concrete target; the test results agree well with those of theoretical analysis.
