Abstract

Thermal numerical simulation of the laminar construction of RCC Dams S.R. Sabbagh Yazdi & A.R. Bagheri Faculty of Civil Engineering, KNT University of Technology, Iran Abstract The use of the Roller Compacted Concrete (RCC) in the core of the body of gravity dams can considerably speed up the procedure of the construction. Since there is no post-cooling treatment for RCC dams, it is necessary to analyze the temperature profile of the concrete body for desired plan of the construction. A diffusive equation is coupled to the concrete heat generation equation in order to solve the temperature field. The discrete form of the equations is derived using Galerkin method by application of piece wise linear approximate function. The solution domain is divided into hybrid structured/unstructured triangular finite elements, considering gradual movement of the top boundary of the concreting. Application of the software in simulation of temperature profile in a typical RCC dam section is also
