| 摘 要： | 根据非饱和膨胀土的分形结构模型，导出了非饱和膨胀土的吸力强度公式，讨论了非饱和膨胀土强度公式的有线性，根据膨胀土的强度特性提出了膨胀土地基承载力公式，运用所提出的承载力公式估算了邯郸和宁夏膨胀土地基承载力值，与实测结果一致，这种膨胀土地基承载力公式可以直接应用于工程实践中。

| Abstract: | The suction strength, which is induced by suction of unsaturated soil, can be obtained based on the fractal model of unsaturated soil micro structure. The nonlinear character of unsaturated soil suction strength is discussed. The formula of bearing capacity of unsaturated expansive soil is pressented by using the lateral pressure of expansive soil and the bearing capacity formula is justified by the loading plate test of expansive soil basement. |
