摘要
本文首先通过坐标轴的旋转、压缩变换，推得了各向异性含水层中井流问题的计算公式．并提出一种基于抽水试验资料，图解和优化相结合的半解析方法确定岩体渗透系数张量及渗透主值的方向．算例表明，这种半解析的计算方法不仅简易、而且有较高的计算精度．
The formula for calculation of well flow in anisotropic aquifer is established by using coordinate transformation of revolve and compression.Based on the information of pumping test a semi\|analytic method for determination of hydraulic conductivity tensor in rock mass is proposed.The example shows that this method iseasy to use and has enough accuracy.
