摘　　要：对嵌岩灌注桩深基坑分别采用理正深基坑软件中的单元计算模块和整体计算模块进行计算分析,结果表明:整体建模计算能充分考虑灌注桩、冠梁、腰梁的整体受力及空间协调性,灌注桩桩长和配筋均可减小。同时,对不同冠梁刚度、腰梁刚度的模型进行整体建模计算分析。结果表明,增大冠梁刚度可以减小桩顶位移,不能减小最大位移;增大腰梁刚度可以减小最大位移,不能减小桩顶位移。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 modeling 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.
