DETERMINATION OF HYDROGEOLOGICAL PARAMETERS BASED ON HYDROCHEMICAL KINETICS METHOD

The determination methods of hydrogeological parameters in the aquifer are mainly involved in pumping test,slug test,water-pressure test and numerical inverse analysis.A new method is developed to determine the hydrogeological parameters.According to transport law of each chemical component in natural groundwater,using transport equation of mineral chemical component,adsorption and dissolution kinetics equation of mineral are developed by the expression of chemical kinetics,chemical thermodynamics and groundwater dynamics.And the analytical expressions of hydraulic conductivity efficient and transmissibility coefficient are denoted by chemical indexes.Based on water quality of research area,hydrogeological parameters of aquifer can be determined by hydrochemical kinetics method.The method is applied to determination of hydrogeological parameters of aquifer in underground workshop area of some pumped storage power station.Furthermore,compared with results of water-pressure test,consequently,validity of the method is testified with wide application.
