Description

Technical Field

[0002] A multi-arch dam is a type of buttress dam, consisting of several inclined arched water retaining panels and buttresses. The arches and buttresses are mostly rigidly connected, forming an over-static structure of the spatial system. The arched water retaining panels often use equal-thickness semicircular arches; the arched water retaining panels have a small thickness, a large span, and are less material-intensive, but also more complex to construct. Temperature changes and uneven subsidence of the foundation will cause stress in the dam body, resulting in higher requirements for the rock foundation at the construction location. At present, multi-arch dams mostly use reinforced concrete structures, which are complex to construct, have a long construction period, high construction costs, and high requirements for the construction environment.
