摘　　要：通过钎杆和球锤直接冲击（凿入）岩石的试验，测定出凿入力波形及凿碎比功。以这种直接冲击的凿碎系统进行凿入分析可以简化其过程。在对这种直接冲击的凿碎系统分析后，得出直接冲击岩石的凿岩效率较高的结论，并给出了最佳入射波形的基本概念。Boring force wave and boring specific power are measured separately through the test that shaft bitand ball hammer impact(bore) the rock directly. After analyzing the boring system generated by the direct impact, it gives us a conclusion that the boring efficiency is better by direct impact on the rock and a basic concept on the best incident wave.
