Piles socketed in soft rock were traditionally regarded as end bearingpiles, and the loads transferred from superstructure were assumed in design to be shouldered totally by the piles.
This paper mainly discuses how to determine the pile length, place the reinforcing steel bar coop and determine the water - cement ratio in construction of pressure - grouting and end - bearingpiles.
