长期以来不少学者对一维的非饱和土壤水入渗运动作了深入的研究,建立了微分方程并求得相应的解.但在生产实际中常遇到二维入渗问题,如在渗管供水条件下的土壤水运动即属于平面二维问题,考虑重力作用时,称为垂直的二维非饱和土壤水运动.本文仅介绍水平的非饱和土壤水二维运动的准解析解及其与垂直二维运动的比较.
For a long time, many scholars have made in-depth studies on one-dimensional unsaturated soil infiltration movement, established differential equations and obtained corresponding solutions, but often encountered in the production of two-dimensional infiltration problems, such as in the seepage tube Under the condition of water supply, the soil water movement belongs to the planar two-dimensional problem, and when considering the gravity, it is called the vertical two-dimensional unsaturated soil water movement.In this paper, only the quasi-analytical solutions of the two-dimensional motion of unsaturated unsaturated soils Vertical two-dimensional motion comparison.
