任意各向异性岩体渗透系数张量的半解析计算

Semi analytic method for conductivity tensor in random anisotropic rock mass

本文首先通过坐标轴的旋转、压缩和再旋转变换，推导出了有越流任意各向异性含水层中地下水三维井流问题的计算公式．在此基础上提出了采用抽水试验资料图解和优化相结合的方法确定任意各向异性岩体渗透系数张量及渗透主值的方向．计算实例表明，这种半解析的计算方法不仅简易，而且有较高的计算精度．

By using coordinate transformation of revolve,compression and again revolve,this paper concludes a formula for calculation of three dimension well flow in random anisotropic rock masses.Based on the information of pumping test a semi analytic method for determination of hydraulic conductivity tensor in random anisotropic rock mass is proposed.The example given in this paper shows that this method is easy to use and quite accurate.
