Design of Nuozhadu Core Rockfill Dam
The core rockfill dam in Nuozhadu Hydropower Station has a maximum height of 261.5 m, and is an ultra-high corerockfill dam in meizoseismal region.The dam has several characteristics, such as relative steep dam slope in upstream anddownstream, complex geological conditions and fine natural soil material particle gradation with higher clay content.The dammaterial, dam structure, seismic measures and foundation treatment are focused in engineering design because of the specialcharacteristics of dam.The special designs of Nuozhadu Dam include taking natural clay soil mixed with artificial gravel asimpervious soil material, upstream dam shell being filled with rockfill containing soft rock, adding stainless steel bars in toprockfill area as an aseismic measure, and adopting high-pressure consolidation grouting with dry grinding thin cement in weakrock zones of dam foundation.
