摘    要:应用非饱和膨胀土一维降雨入渗模型,模拟膨胀土边坡在降雨入渗条件下的水分运移规律,通过数值计算, 求得边坡在任意时刻任意位置的体积含水率;并分析了降雨强度、水分扩散率以及导水率变化对边坡水分运移的 影响.计算结果可以用矩阵的形式和三维空间曲面的形式表示出来,方便应用.

关 键 词:膨胀土  非饱和渗流  基坑边坡  降雨入渗

Abstract:This paper proposed a one-dimension model simulating the regularity of moisture flow under rainfall conditions.Water content by volume had been gotten in any depth and at any time through numerical analysis.The effect of rainfall intensity,water diffusivity and hydraulic conductivity to the water distribution were also analyzed.The result could be shown in the form of matrices and three-dimension curves.
Keywords:expansive soil  unsaturated seepage  excavation slope  rainfall infiltration
