摘要
本文对渗流的数值模拟中遇到的边界积水问题进行了理论上的推导,进而在通用的二维渗流模型SWMS＿2D中实现了该边界的处理,并通过典型算例和实际应用对程序的正确性和实用性进行了检验。研究结果表明积水边界条件在SWMS＿2D中的实现是正确和有效的。
This paper did some theoretical studies on water-ponding boundary model, and then applied the boundary model in SWMS_2D, which is a numerical model for simulating water flow and solute transport in two-dimensional variably saturated media. In order to validate the effect and correctness of the boundary model, a typical example problem was simulated. The results were reasonable on the whole. Then, further testing works were conducted by using the model to simulate the water table depth in FILTER^(\) experiment carried out in Australia, and good coincidence was shown between simulating values and the experimental data. Thus it indicats the boundary model is effective and applicable.
