摘要 采用一维非饱和地下水在重力作用下的不稳定运动模型,来模拟降水在土壤中的渗透过程。调整各种与渗流过程有关的物理参数以及考虑蒸发的影响,采用理论上的计算结果来解释降水在土壤中渗流达到稳定的过程。以昌黎台为例,采用褶积滤波和多元回归的方法来定量分析降雨对视电阻率的影响,为定量分析实际资料提供一定的参考依据。 A simple one-dimension model considering fluid movement in unsaturated soils is proposed to simulate the rainfall infiltration process and explain its possible effect on apparent resistivity of the Earth. A convolution filtering method is adopted to analyze rainfall effect on apparent resistivity. As a case study, the result of the Changli Station is reported. The study may provide information for the quantitative analysis of geoelectric observation data.
