Description
Technical Field

Background
Concrete faced dams have been widely used in hydraulic and hydroelectric engineering. The concrete panel is used as an anti-seepage structure of the dam, and the integrity of the structure directly influences the safety of the dam, the benefits of a reservoir power station and the like. The cracks of the panel are a main failure mode of the panel, and the main reasons for the cracks are structural cracks formed by over-stress or uneven stress and concrete cracks caused by temperature stress and drying stress.
