根据实验得到的运动弹丸在多层复合介质中不同深度爆炸时产生的弹坑形状、体积及破坏面积，对破坏效应进行了理论分析，建立了弹丸在多层复合介质中的爆炸破坏分区；考虑主要影响破坏效果因素条件下应用量纲分析方法，并结合实验数据得到了破坏参数与比炸深的无量纲关系式和关系曲线，由这些曲线能够方便地查找所需最佳破坏效果对应的比炸深，在相同条件下，该结果可推广到类似目标的爆炸破坏效应分析。

Based on the shape，volume and area of dent in multi-layered target created by kinetic projectile explosive, the damage effect was analyzed. The damage zoning was founded in multi-layered target. The experimental data were analyzed, then relation curves of diversified damage parameter with blasting depth worked out by using the dimensionless method. Through those relation curves, the blasting depth corresponding to the optimal damage effect can be found easily. This method can generalize to other blasting damage effect analysis.
