| 中文摘要: |
| 本文在评价了现有非饱和土有效应力参数确定方法的基础上，提出了一种新的求解方法。这种方法直接从非饱和土应力应变关系、孔隙气压力和孔隙水压力入手，推导出反映剪应力和球应力的有效应力参数公式。同时根据武功黄土试验资料进行了整理，所得有效应力参数规律性较好。 |
| 英文摘要: |
| Based on the assessment of existing methods for determining the effective stress parameters of unsaturated soil, a new method is proposed. By using this method the parameters reflecting the shear stress and sphere stress can be directly deduced according to the stress-strain relationship, pore air pressure and pore water pressure. The result is verified by experimental data. |
