基于多孔非稳定抽水试验的缓倾层状含水层各向异性渗透参数计算
Calculation of anisotropic permeability parameters of flat pitch aquifer based on multiple-well unsteady pumping test
摘要
Abstract
The parameters of anisotropy of hydrogeology can be obtained through drawdown-time relationship of multiple-well pumping test.In this paper,the multiple-well unsteady pumping test data are used to calculate the main direction and specific value of permeability tensor by Matlab incorporating with non-axial anisotropic permeability tensor theory.The final result which is consistent with the actual drawdown condition is obtained after contrastive analysis from two separate test results,with the main direction range of [8°,18°],and the Ky/Kx range of [7.5,13].The calculation method proves to be feasible and rational for the non-axial anisotropic permeability tensor theory.It points out that the key parameter to calculate anisotropic permeability parameters is the intercept of s-lnt curve.关键词
