摘要
Abstract
Pumping test is a conventional method to obtain local hydrogeological parameters.Based on the field pump-ing test of Nafeng trunk line of Guangxi Water Resources Allocation Project around Beibu Gulf,a porous pumping topological pipe network model was established,and the SQP optimization method was applied to the inversion cal-culation of permeability coefficient.Finally,the permeability coefficients of confined aquifer in parallel fault direc-tion and vertical fault direction in the project area were obtained.Compared with the measured data,the inversion effect is good.The anisotropic permeability coefficient can be obtained by this method,which provides a new idea and method for inversion of groundwater parameters in pumping test.关键词
