一、有界含水层S～lgt曲线特征关于有一条隔水边界的S～lgt曲线已有论述,在此基础上,笔者对多边界的几种曲型S～lgt曲线的线型进行分析表明,它是一条反映边界条件的折线(图1)。现从图1中位于两条夹角为60°的隔水边界之间的抽水井为例予以阐明。设承压含水层为等厚、均质。当t足够 First, the characteristics of S ~ lgt curves of bounded aquifers have been discussed on the S ~ lgt curve of a water-permeable boundary. Based on this, the author analyzes the linear patterns of S ~ lgt curves of several curved lines in multi-boundary , Which is a polyline reflecting the boundary conditions (Figure 1). An example is shown in Figure 1 using a pumping well located between two water-blocking boundaries at an angle of 60 °. Supposed aquifer is equal thickness, homogeneous. When t is enough
