New stress–strain model and intelligent quality control technology for cemented material dam

Cemented material dam (CMD) can fully utilize local sand, gravel, and rock materials for dam construction. It has many advantages such as flood overtopping without failure, environmental friendliness, economic savings, rapid construction, and so on. It has been rapidly popularised and applied to domestic and foreign projects since it was put forward by the first author. This paper illustrates the reasons for the proposal of CMDs, puts forward the stress–strain model of the cemented mixture and the intelligent system of production quality control, presents the model test results for CMD against flood overtopping, and introduces the practice of dam construction with low-strength soft rock and weathered materials.
