Study on Filling Material Strength and Dam Failure Characteristics of Loess Dam

Applied Sciences, 2023
In the Loess Plateau region, loess, as a widely distributed building material, is often used as a filling material for dams. When the water level reaches a certain height, the body of a dam is prone to shear failure due to the penetration of water.
