主 题：Upper Gotvand Dam seepage analysis gypsum veins 3D model discharge flux
摘 要：Upper Gotvand Dam is constructed on the Karun River at the south west of *** this paper,2D and 3D models of the dam together with the foundation and abutments were established,and several seepage analyses were carried ***,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 *** was disclosed that the discharge fluxes obtained from 2D and 3D analyses are not similar,and the discharge flux in 3D model is about four times that of the 2D ***,the 3D model locates the phreatic surface somewhat higher than the 2D *** means that the 2D model estimates lower pore water pressure pattern in comparison with the 3D *** may be attributed to the fact that with 2D model the lateral components of vectors of seepage velocity are *** the current case,the rate of increase of discharge flux due to dissolution of gypsum veins was obtained to be a thirdorder function of the aperture *** spite of the fact that the grout curtain is designed to be about 170 m deep,however,complete dissolve of gypsum will severely increase the discharge flux through the foundation ground.
