摘　　要：将半无限弹性空间中的Geddes解与Mindlin解应用于刚性桩复合地基沉降计算,考虑了桩的荷载传递特性、桩侧摩阻力及荷载作用深度等对复合地基沉降计算的影响。实例验证表明,理论计算结果与实际沉降观测值基本吻合。The new method, combining the Geddes with the Mindlin solution in the semi-infinite elastic space, is used to calculate the settlement of the rigid pile composite foundation, in which such factors as the load transmission, the skin friction and the load influencing depth of pile and so on are considered. From the calculation of a project, it is shown that the calculated results is good agreement with the test results.
