The dam of Three Gorges Project is a concrete gravity dam with the crest elevation of 185 m,the maximum height of 181 m and dam axis length of 2 309.5 m.The dam consists of spillway,powerhouse,non-over flow,ship-lift,temporary ship-lock,left diversion wall and longitudinal cofferdam blocks.Some key techniques relating to dam structure design are presented,including hydraulics of flood discharge structure,dam joint design,layout and structural type of penstock,deep anti-sliding stability of dam foundation,reconstruction of temporary ship-lock and closed drainage and pumping of dam foundation.
