摘　　要：为研究弹体在钢筋混凝土中的侵彻过程，以靶体中钢筋为支撑，在钢筋混凝土靶体中预埋了呈网格状分布的格栅系统，借助LED灯的表征作用，在高速摄影设备的辅助下，测试了弹体在靶体中的侵彻通道和最终侵深；通过经验公式和现场的靶体解剖验证了弹体侵深的测试结果，论证了格栅测试方法的有效性。In order to study the KEP＇s（ Kinetic Energy Penetrator） penetration in steel reinforced concrete, a grid system was pre-embeded with the support of the steels. With the help of LED lamps and high-speed photography technique, the penetration progress and the final penetration depth were studied. The depth of penetration was finally gained by the LEDs＇ winking, which was validated by empirical formula and direct measurement. The ex-periment results illuminated that the grid method was effective.
