Nowadays,with the economic developed and environmental issues valued. At present,more and more researchers studied on the environmental issues,and the range of the studay became wider. It is one of hotspots that considerring Water-Rock Interaction in the environmental issues. By the researches on the features and methods of solute migration under the water-rock interaction,it can determine the formation of chemical composition in groundwater and possibility of formation of solid-phase composition, investigate the changes of groundwater's chemistry under the influence of natural and human factors, forecast how human activities influenced groundwater quality, and solve the environmental problems which affected human health and retarded economic development.Based on understanding and summarizing of the situation of study home and abroad, the main pionts are as follows:(1)Referred to relevant references home and abroad to learn about the Water-Rock-Interaction and its researching methods, summarized and discussed the direction of geochemical modeling and simulation software, the Water-Rock-Interaction classification, experimental study and research trends.(2)Summarized and discussed the characteristics of rock mass fractured media, simulation of fracture network, theory of seepage, solute transport and geochemical modeling.(3)Solving the inverse geochemical simulation by the MATLAB optimization toolbox.(4)built the Model of mineral dissolution-precipitation-transportation in the stable flow and unsteady flow, introduced numerical stimulation of coupled model, written the FORTRAN program which had sovied the models as mentioned above.Given the spatial and temporal distribution of solute concentration field and mineral dissolution-precipitation quantitative analysis,forecasted the range and trends of mineral's dissolution-precipitation-transportation,and summed up the change law.
