Experimental investigation into rockfill dam failure initiation by overtopping [PDF]
: Rockfill is the most abundant building material. It is often used for water retention under different contexts, such as dams, embankments or drainage systems. Climate change may cause water levels to rise in reservoirs.

The Cemented Material Dam: A New, Environmentally Friendly Type of Dam
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 way for both the dam and the area downstream.

This study investigates the macro‐meso mechanical evolution of dam rockfill under the coupled effects of coarse‐particle content (P5) and confining pressure (σ3) using large‐scale triaxial tests and PFC3D simulations. The results show (1) shear strength and particle breakage depend synergistically on σ3 and P5.

Construction Problems with an Earth and Rockfill Dam [PDF]
Earth and rockfill dams became popular in the 1960\u27s primarily because of increased heights of dams, poor foundation conditions that rule out concrete dams, and vast improvements in excavation and vibratory compaction equipment.

New Type of Dam for Longitudinal Reinforced Rockfill Dam and Its Operation Safety Analysis
After a long time operation, a conventional earth rockfill dam (e.g. homogeneous dam or core wall dam) may suffer from a lot of dam diseases such as dam-break, overtopping, landslides and leakage. On the basis of a large number of practices of rebuilding

Field compaction tests on rockfill dams based on surface settlement method
Changheba Dam has been a world-class high rockfill dam in China with the second highest height and the first largest filling volume in the world. The dam body is the dam shell filled by the local rock, and its compaction quality directly affects the dam ...
