The unit calculation module and the whole calculation module in Lizheng deep foundation pit software were used to calculate and analyze the deep foundation pit of rock-socketed piles respectively.The results show that the whole force and spatial coordination of the pile,crown beam and waist beam can be fully considered in the whole model-ing calculation,and the pile length and reinforcement can be reduced.At the same time,the whole model of different crown beam stiffness and waist beam stiffness was calculated and analyzed.The results show that increasing crown beam stiffness can reduce pile top displacement,but not the maximum displacement,and increasing waist beam stiffness can reduce the maximum displacement,but not the pile top displacement.
