Determining of the REV for fracture rock mass of very low ductility

Seepage problem of fracture rock mass is one of the front topics in hydrogeology and engineering geology.The equivalent porous medium model plays an important role in the study and engineering application of fracture rock flow.The key of its application lies in design of a correct fracture rock mass model,which means a representative element volume(REV).The code FractureToKarst,which is a main analysis tool in this paper and developed by Prof.YU,is a DFN(Discrete Fracture Network) software.Accor...
