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、有效的好方法 Due to the introduction of similar conditions, we can reduce the size of seepage area proportionally, speed up the evolution of seepage flow and shorten the time of long seepage process. In addition, the preparation of model is simple and easy to control and Measurement, and can change the magnitude of the parameters by a similar ratio to improve the measurement accuracy. This experiment played a very important role in the study of water resources in the second Songhua River mainstream area and also confirmed that indoor similar simulation tests are a convenient, economical and effective method for studying groundwater seepage problems
