摘要
分析了聚能射流和爆炸成形弹丸(EFP)在侵彻岩石时的不同特点,提出了用EFP在岩石中侵彻圆柱形深孔的新方法.研制了一种新型聚能装药,并用它对多种岩土进行了侵彻试验,得到了长径比为10—20的圆柱孔,并指出了侵彻深度与岩土容重的相关性.
On the basis of analyzing different characteristics of penetrating rocks by using jet and EFP of shaped charge, a new approach is presented to make a deep cylindrical perforation in rocks. A special device of EFP—shaped charge has been developed, which has been employed to perform tests of penetrating various kinds of rocks and soils, and cylindrical perforation with ratio of length to diameter 10—20 were formed. Also the relationship between the perforation penetration and bulk density of rock and soil are reported.
