目前研究渗流与地下水方面的问题,主要包括解析法、数值法(有限差分法和有限元法)和模拟法三大类,下面主要结合工作谈一点物理模拟的情况。模拟(包括模型)试验的内容很多,应用的范围很广,按方法可以分述如下:一、砂槽试验这种方法应用比较早,为人们所熟知。根据试验的目的不同,研究农田排水多做成长形的槽,或者方形的槽,研究井的作成扇形(或半园形)的槽。槽中装砂、或其他膨胀性很小的 At present, the study of seepage and groundwater problems, including analytical methods, numerical methods (finite difference method and finite element method) and simulation of the three major categories, the following combination of work to talk about a little physical simulation of the situation. Simulation (including the model) test a lot of content, the application of a wide range of methods can be divided as follows: First, the sand tank test This method is relatively early, is well known. According to the different purposes of the experiment, the study of farmland drainage and more to do the growth of the slot, or square slot, research wells made of fan (or semi-circular) groove. Slot filled with sand, or other little expansion
