| 摘 要： | 根据圆柱体本坐标的极点条件构造了两组合适的位移函数，分别表下圆板－板下地基与外围土的位移，使在任意载下圆心处的应力应变不再奇异，并根据复合地基的特点，提出了将桩－土模拟成各向性体，计算圆板应力和变表的方法，并给出了算例。

| Abstract: | In this paper,to make the stress and strain at the pole of a circular plate under arbitrary load no longer discontinuous,two groups of displacement functions are suggested to express the displacement of the circular plate and that of the soil beneath and around the plate respectively.With this method the analysis of a circular plate on a composite foundation is carried with the column and soil being considered as anisotropic media,a calculating example is given. |
