Rock-socketed pile is a special form of pile foundation,and its construction technology control requirements are very important to the design of rock-socketed pile.Combining with the experience of engineering examples,aiming at the problems in the design and construction of precast core-column rock-socketed pile,such as selecting the slope of precast pile,controlling the penetration of final hammer,regulating the thickness requirements of sediment in boreholes and determining the mud index,by enumerating the engineering examples,calculating the axial bearing capacity and analyzing the standard formulas,the key points and recommended values of the key parameters in the design process of precast rock-socketed piles are obtained.In addition,common problems in construction and treatment measures are given.
