摘要
在库水位下降的土坝非稳定渗流计算程序的基础上,编制了库水位升、降的非稳定渗流计算程序。着重介绍程序编制时的处理方法,如水位上升时采用恢复结结点,水位下降时采用丢弃结点等。本程序适合堤坝非稳定渗流计算及河流对矿坑地下水动态影响的渗流计算。为论证程序的可靠性,利用文献[3]中的粘滞流模型试验及差分法计算进行比较,结果基本相符。程序已应用于三个实际工程。
Based on the existing unsteady seepage program for earth dams with fall in water level, unsteady seepage program with rise and fall in water level is worked out. The program fits for seepage flow computations in levees and dams and for seepage flow computations of the dynamic state of mine groundwater influenced by river. In this paper, the handling methods in computer programing are emphatically presented, such as application of recovery nodes during rising water level and abandoning nodes in case of fall in water level etc.. In order to prove the reliability of the program, comparison with the data of viscous flow model test and difference methods in reference[3], the comparative results are in agreement basically. The program has been utilized in three practical projects,
