When pile foundation encounters the ups and do-wns integrity hard rock, it badly affects the efficiency of making hole and has an impact on RAM frequently. This paper systematical y solves the difficulties using improved techniq-ues of dril bore and new design of RAM. It may provide pr-actical base and construction experience for the similar ge-ological construction.
