| 摘 要： | 将非散体材料复合地基（水泥搅拌桩、粉喷桩等）模拟成各向异性弹性体。根据圆柱体柱坐标的极点条件，取样条函数为复合地基的位移函数，而外部土体用半解析函数来模拟。最后对圆板-成层复合地基系统进行了分析。

| Abstract: | In this paper, composite foundation is simulated by anisotropic elastic solid. According to the condition at the origin, the spline functions are developed to investigate composite foundation. The semi-analytical functions are used to analyse the semi-infinite soil beyond the composite foundation. Finally, numerical analysis of the circular plate-foundation system is done. |
