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).
