相似模拟试验在地下水运移及参数求解中的应用

地下水渗流问题研究方法中的相似模拟方法，由于相似条件的引入，使我们能够成比例的缩小渗流区尺寸，加速渗流演变速度，缩短漫长渗流过程的时间；另外，模型的制备简单，便于控制和测量，并能通过相似比例改变参数的数量级，提高测量精度，本次试验在第二松花江干流区的水资源问题研究中起到了很大作用，同时也证实了室内的相似模拟试验是地下水渗流问题研究中的一种方便、经济、有效的地方法。

The Application of Analog Simulation Tentative Research in Groundwater Migration Mechanism and Patameter Solution

The analog simulation method is used in researching groundwater influent. Because the model is inducted similar condition,it can in proportional diminish the size of influent region, accelerate the groundwater influent velocity, and shorten the long time of influent process, otherwise, the model can be easily prepared, controled and measured. We can alter the order of magnitude of the groundwater parameter through the similarity ratio. The test have played great effect in the water resources research of the principal river area of the seconed song hua jiang river .At the same time ,it also demonstrate the indoors analog simulation tentative is a economic and effective method in researching the groundwater influent problems.
