Experimental Research on Solute Transport in Fractured Rock Masses

The difference of solute transport between in porous media and in fractured media is put forward and the solute transportation mechanism is discussed in this paper based on the concentration distribution of Nacl. Then a rectification on the theoretical model of solute transportation in porous media is given, and a mathematical model of solute transport in a single fracture is presented and the diffusion coefficients of Nacl solute are deduced. In the end of this paper, the modified numerical model is validated by the above experiment.
