线型聚能切割索在拆除爆破中的应用

Application of the Linear Shaped Charge on the Demolition Blasting

作者通过线型聚能切割索对不同介质爆破切割模型试验，进而应用于爆破拆除地下钢筋混凝土管，取得了良好破碎效果．并提出了线型聚能切割索产生金属射流对非均质复合材料的爆破机理探讨，为扩大聚能切割索的应用提供了一定的理论依据。

Experiments of blasting models to cut different media by the linear shaped chargeare donc, and the linear shaped charge is used to cut underground concrete pipes with a good fragmenting effect. The demolition mechanism of metal jet generated by the shaped charge to cut noneven compound materials is suggested. It provide a theoretical foundation for expanding the rangeof application of the linear shaped charge.
