水位降深
1.
A formula for emendation of drawdown in pumping wells for analysis of 2-D finite difference method with rectangular grid or unstructured polygon grid is proposed by introducing the approximate analytical solutions of unsteady well flow suggested by Theis.
采用该公式分别对小尺度模型和大尺度模型进行分析,计算结果表明,常规数值法得到的井中水位降深明显偏小,甚至只有实际井中水位降深的1/3~1/4,而经本文公式校正后得到的井中水位则与实际水位接近,相对误差较小,具有较高精度。
2.
