摘　　要：采用HYDRUS-2D模型进行模拟计算渠系水渗漏量,考虑饱和流与非饱和流的联合求解的渠道渗漏二维数值模拟方法,以山西省庞庄灌区碱刘断面为例,模拟了不同运行情况下渠道两侧的地下水土壤水动态变化,并与文献中的试验数据和结果对比分析,验证了数值方法模拟渠道渗漏的可靠性与参数选择的合理性。In this paper, the HYDRUS-2D model is used to simulate the canal water leakage, and the saturated flow is simulated combined with the unsaturated flow in two dimensions. As an example, the method is used to analyze the seepage of the Jianliu section on the second Main Canal of Pangzhuang Irrigation District in Shanxi Province under different conditions. The simulation result and comparison with the experimental data and results in literatures has proved the reliability of numerical method for canal seepage and the rationality of parameters selection.
