The influence factors on the penetration depth of shaped charge jet were summed up by analyzing the formation of shaped charge jet and penetration. According to the factors and the condition of engineering practice,a sort of the flexible and linear shaped charge cutter was designed. The target steel plate with the thickness of 10 mm was penetrated through by the linear density 158 g · m -1 and blasting height 2.4 mm of the flexible and linear shaped charge cutter with lead shell from experiments. This type of cutter was used for cutting inclined brace steel tube in the steel tower blasting demolition that made an accurate collapse. Finally, the inclined brace steel tube with thick wall was penetrated through by the cutter, the direction of collapse was inerrability and the steel tower blasting demolition was very success.%从聚能射流形成及侵彻理论出发,总结了影响聚能射流穿深的因素,根据这些因素的分析及工程实际条件,设计并制造了一种铅质外壳柔性线型聚能切割器,对10 mm厚的45′钢板和斜支撑上截取的钢板进行聚能切割实验,发现线密度为158 9·m-1,炸高为2.4 mm的柔性线型聚能切割器完全贯穿45#钢板和斜支撑上截取的钢板;把此种柔性线型聚能切割器应用到钢管塔架立窑爆破拆除的斜支撑处理中,该柔性线型聚能切割器完全贯穿了斜支撑厚壁空心钢管,确保了结构倒塌方向无误,成功地辅助了钢管塔架爆破拆除的实施.
