考虑无压含水层各向异性和迟后反应的纽曼方法,克服了布尔顿方法的一些理论上的缺陷和应用上的困难,是计算潜水含水层水文地质参数的比较理想的方法。用纽曼法求参时,以往都使用σ=10~(-9)计算的A组曲线和B组曲线的标准量板。然而,在实际的松散地层中,σ的数量级一般在10~(-2)左右,而且抽水资料中间的水平段表现也不明显。因此用对标准曲线
The Newman method considering the anisotropy and late reaction of pressureless aquifer overcomes some theoretical defects and application difficulties of the Bourdon method and is a ideal method for calculating the hydrogeological parameters of submerged aquifers. Newton method for reference, the past use of σ = 10 ~ (-9) calculation of the A group of curves and B group of standard curve plate. However, in actual loose formations, the magnitude of σ is generally around 10 ~ (-2), and the horizontal section of pumping data is not obvious. So with the standard curve
