To reduce effectively the design and construction risks of rock-socketed piles in port and waterway engineering and save the engineering cost,we can determine the pile length by the graphic checking method,and obtain the minimum distance and corresponding coordinate of points considering the deviation of pile top,the inclination angle and torsional angle of the longitudinal axis by the formula checking method based on programming,thus to meet the design and construction demands of pile calculation and optimization adjustment of rock-socketed piles.
