| 摘 要： | 文章采用Tempe仪测定了某滑坡滑带土的水质量分数与基质吸力的对应关系,利用指数衰减函数对该土水特征曲线进行描述,并确定了该土样的残余水质量分数;结合土水特征曲线的性质对指数衰减函数中的参数的物理意义作了明确的定义,结果证明该公式简单明了及适用性强。

| Abstract: | The relationship between moisture content and matrix suction of the sliding zone soils of a landslide is obtained based on the measurements with the Tempe equipment.The soil-water character-istic curve is described with the exponential decay function and the residual moisture content of the sample is calculated.The physical significance of all parameters in mathematic derivation is defined based on the characteristic of the soil-water characteristic curve.The presented equation is simple and suitable for using. |
