THE EQUIVALENT PERMEABILITY COEFFICIENT AND IT'S APPLICATIONS BASED ON THE STOCHASTIC STRUCTURE MODEL OF KARSTIC ROCK

Based on the stochastic structure model of karstic rock established with the date from the on-the-spot measurement, the concept of equivalent permeability coefficient is described in details. The distributing rule of leakage can be got by repeating calculation several times. At last, an example is offered to explain the usage of the method in actual engineering.
