Karst development models and reservoir anti-seepage design in a hydro-junction construction site in Qianzhong district

The rocks in a hydro-junction construction site in Qianzhong district are carbonate and deep cutted by river,which is very common in this region.Controlled by lithology,the corrosion is going on only in carbonate rocks layer and therefore the karst is multilayer,and the non-carbonate rocks layers are good confining beds,which is very good to anti-seepage.The fault F3 in the dam site is compression fault and has no damage to the multilayer karst system.However,this causes some of the w...
