| 摘 要： | 采用以土壤水势为自变量Richards方程、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，以山东省位山灌区二干渠碱刘断面为例，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，通过水量平衡分析、与动水法渗漏量比较、与实测地下水位比较等，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。经

| Abstract: | Numerical simulation is an important method to understand the seepage from canals. In this paper, the saturated flow is simulated associated with unsaturated flow in two dimensions, which is based on the Richards equation with the independent variable of soil water potential. As an example, the method is used to analyze the seepage of the Jianliu section on the second Main Canal of Weishan Irrigation District in Shandong Province under different conditions. With the validating of the water balance analysis, the seepage experiment and the groundwater table measured, the simulation result is well and the preferences are reasonable. |
