Seepage analysis of Upper Gotvand Dam concerning gypsum karstification (2D and 3D approaches)

Jamshid SADREKARIMI, Majid KIYANI, Behnam FAKHRI, Mohammad Javad VAHDATIRAD, Amin BARARI

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 1, Pages 71-78 doi: 10.1007/s11709-010-0083-5

Abstract: Then, the gypsum veins that are scattered throughout the foundation ground were included in the models, and the seepage pattern, considering the dissolution law of gypsum, was analyzed.In the current case, the rate of increase of discharge flux due to dissolution of gypsum veins was obtainedof the fact that the grout curtain is designed to be about 170 m deep, however, complete dissolve of gypsum
