| 摘 要： | 利用能够控制基质吸力的4联式非饱和土直剪仪，对清江流域古树包滑坡滑带土体进行了不同固结应力条件下土-水特征试验，得出了土-水特征曲线并进行了函数拟合。结合土-水特征曲线拟合函数，经过数学推导确定了函数中各个参数的物理意义，建立了能够同时反映固结应力、基质吸力和含水率之间关系的函数表达式，弥补了其他方法不能考虑固结应力的缺陷，对补充和发展土-水特征曲线试验和理论具有重要意义。

| Abstract: | The experiments of soil-water characteristics curves are made under different consolidation pressures for sliding zone soils of Gushubao landslide in the Qingjiang valley,with an advanced unsaturated soil shear instruments which can control suction.The experiments show clearly the influences of consolidation pressure on the soil-water characteristics curves.The varied consistent functions have been established from the experiment data of soil-water characteristics curves;and the physical meanings of paramet... |
