Abstract :
A new drilling technique used in a wider range of application auger-percussive-rotary drilling technique is defined based on operation experiences and combined with the theoretical analysis in the anchor engineering of soil and rock. After summarizing the advances of this technique some existing problems encountered in practice are presented to improve.
