Abstract :
If there were hard boulders or rock layers distributed in the formation of pile foundation, it was difficulties to the drilling hole-pile. Blasting before drilling was used in hard rock layer; underwater control millisecond initiation was used in hole-pile; cumulative blasting was used in hard boulders; blasting was used in outshoot stones. Construction efficiency was greatly improved.
