研究黄河水测渗补给地下水,以往多用稳定流理论。本文拟介绍用非稳定流理论的研究方法、理论公式,研究黄河水测渗补给及其实用价值。本文根据专门性的黄河测渗研究工程,将试验段刻划为一个“二元结构”模式多孔介质渗流模型。并建立了相应的数学模型。反演以推求水文地质参数,正演以藕合水位信息,既验证了参数的可信性,又识别了模型的合理性。由此计算的测渗量具有一定的精确性。用非稳定流理论来研究黄河水测渗补给地下水系统,在国内还是初次,其理论公式及计算结果,具有一定的理论研究价值及实用意义。
Study of the Yellow River water seepage to groundwater, in the past with more stable flow theory. In this paper, we introduce the research methods and theoretical formulas of unsteady flow theory to study the water supply of the Yellow River and its practical value. Based on the special project of the Yellow River seepage survey, this paper characterizes the experimental section as a porous media seepage model of “binary structure” mode. And established the corresponding mathematical model. Inversion was used to deduce hydrogeological parameters, and the information of water level coupling was staged to validate the credibility of the parameters and the rationality of the model. Calculated infiltration measured with a certain accuracy. Using the theory of unsteady flow to study the groundwater system of the hydrological seepage in the Yellow River is still the first time in China. The theoretical formula and calculation result have certain theoretical research value and practical significance.
