Basis calculation results of thermal stress of roller compacted concrete for nuoctrong dam by using CESAR- LCPC software

Abstract

    The RCC dams have been used very popular in the World because they have some advantages such as short construction time, low costs, using of local materials for dam body. In Vietnam we have just constructed some dams in the North and Central namely: Dinh Binh, Pleikrong, Son La, Ban Ve and so on. The Quality of dam construction is depended so much on the design and implementation methods. In this paper will show the calculation results of limitation of placing height and the maximum temperature of layers that can prevent the crack due to thermal stress. Keywords: Construction, Crack, Thickness of Layers, Roller Compacted Concrete, Thermal stress.
