    摘要:

    本文根据质量守恒定律和求解非饱和水力传导度的瞬时剖面法的思路,提出了一种求解非饱和弥散系数的实验及其计算方法。通过野外实验说明该法是有效的,甚至对于非均质性或具有空间变异性的土壤都适用。该法具有两个方面的优点:一是实验和计算简单;二是通过一次实验可求出一组弥散系数和孔隙水速度的数值,从而可寻找二者之间的相互关系。数值模拟结果表明,由该法所求的参数是可靠的。

    Abstract:

    Based on the law of mass conservation and the transient profile method used in determining the unsaturated hydraulic conductivity of soil, the method for determining the unsaturated dispersion coefficient of soil was developed. It was shown by field experiments that the method was effective in estinnating unsaturated dispersion coefficient under field condition, even for heterogeneous soils or those of spatial variability in their properties. The method has two advantages, i.e. simplicity in experimentation and computation and values of D and V and their relationship for a group of plots being able to be obtained from an experiment. Modelling experiments have shown this method is, reliable.
