众所周知,一些计算松散含水层参数的方法需用对数或半对数纸和其它事先准备好的表格。作者发现在能相当准确地绘出时间——降深曲线的情况下,可用直线法确定含水层的参数。直线法的推导过程承压含水层的降深(S)以下式表示: It is well known that some methods for calculating loose aquifer parameters require the use of logarithmic or semilogarithmic paper and other forms that are prepared in advance. The authors found that the parameters of the aquifer can be determined using the straight-line method when the time-depth curve can be plotted accurately. The derivation of the straight-line method is as follows:
