Three-dimensional seismic response analysis of a concrete-faced rockfill dam on overburden layers

Dakuo FENG, Ga ZHANG, Jianmin ZHANG,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 2, Pages 258-266 doi: 10.1007/s11709-010-0031-4

Abstract: Reasonable seismic response analysis of a high rockfill dam is of great engineering significance in guidingits design and ensuring its seismic safety during operation, especially of a concrete-faced rockfilldam (CFRD) on overburden layers.The results indicate that: 1) the amplification coefficient along the dam axis gradually increases withthe altitude, and reaches maximum at the dam crest; 2) the vertical residual deformation mainly exhibits

The Cemented Material Dam: A New, Environmentally Friendly Type of Dam

Jinsheng Jia, Michel Lino, Feng Jin, Cuiying Zheng

Engineering 2016, Volume 2, Issue 4, Pages 490-497 doi: 10.1016/J.ENG.2016.04.003

Abstract:

The first author proposed the concept of the cemented material dam (CMD) in 2009.This concept was aimed at building an environmentally friendly dam in a safer and more economical wayfor both the dam and the area downstream.The concept covers the cemented sand, gravel, and rock dam (CSGRD), the rockfill concrete (RFC) dam (or the cemented rockfill dam, CRD), and the cemented soil dam (CSD).
