甘肃黑方台黄土水分运移规律模拟

doi:10.13866/j.azr.2018.04.08

摘要/Abstract

摘要： 以室外试验为基础,应用饱和-非饱和土壤水分运移理论,利用Hydrus软件对甘肃黑方台包气带水分运移规律进行数值模拟,分析土壤剖面不同深度处含水量变化规律,将模拟结果与实测结果进行对比分析,并将拟合参数应用到两种不同的介质中。结果表明:① 土壤含水率呈峰谷波动变化;② 均质黄土层和上覆5 cm厚的粉质壤土的黄土层中,土壤水分入渗率和潜水蒸发率均随潜水埋深的增加而减少,在潜水埋深300 cm以下时,两种介质的土壤水分入渗率趋于同一值,含粉质壤土的潜水蒸发率小于均质黄土的潜水蒸发率。表明该含水量的变化具有时空特征,土壤水分入渗率、潜水蒸发率随着潜水埋深变化,其规律整体相似,这对研究滑坡水分分布具有重要意义。

Abstract: In this study,a numerical simulation of vadose water migration in Heifangtai of Gansu Province was carried out based on the analyzed results of the saturated-unsaturated loess moisture migration by using the Hydrus-1D software.The study was based on the field experiments and the saturated-unsaturated soil moisture migration theory.The simulation was verified using the field experiments,the fitted parameters of two kinds of soil were applied,and the simulated and measured values of soil moisture content were compared and analyzed.The results showed that; ① The soil moisture content changed in a fluctuation way; ② Soil water infiltration rate and the phreatic water evaporation rate were decreased with an increase of phreatic water depth; water infiltration rates of the two kinds of soil tended to be similar when the phreatic water depth was deeper than 300 cm,and the phreatic water evaporation rate of silty loam was lower than that of homogeneous loess.In conclusion,the spatiotemporal variation of soil moisture content was significant.The study results could be referred in researching the water distribution and change of landslide.
