Abstract: The subsurface conditions of the Taoyuanchun Residential Development are complicated. The bored castinpace piles are to be installed in the highly developed karst terrain with rock caverns and pinnacles. The combination of rotary and percussion drilling techniques are used found to be the optimum installation method. This paper summarizes the construction techniques of this combination method.
