| 摘 要： | 基于饱和-非饱和渗流理论,针对复杂层状地质体内不同渗透特性介质的空间分布情况,以克立格插值建立模型,并对水流在其内部的动态变化进行数值模拟,分析了地质体内压力水头的分布变化规律,进而得到水流在非均匀地质体内的渗透变化规律。数值模拟结果表明:均匀地质体内压力水头连续分布,非均匀介质体内的压力水头在不同渗透性介质的交界面处出现转折,渗流速度的方向也随着介质的不同分布发生改变。

| Abstract: | Based on saturated-unsaturated seepage theory,aimed at the spatial distribution of complex layered geological media with different permeability,the paper used the method of Kriging interpolation to build model,carried out numerical simulation on water flow in its internal dynamics and analyzed the distribution of pressure head in the geological body,and further got the seepage rule of Non-uniform geological body.The simulation results show that the distribution of pressure head in the uniform geological bod... |
