Study on the Computation Method of Temperature Field of RCC Dam
Based on the construction property of rolled compacted concrete dam casted by layer, three- dimensional finite element relocating mesh method is provided to simulate construction process and compute temperature field. The computation model of relocating mesh method is expatiated in detail. According to the thermodynamic properties of RCC materials, the feasibility and error of relocating mesh method are analyzed and demonstrated. The computation results in this article are verified by means of the temperature observation data of one RCC arch dam. The results show that the temperature field computed by three-dimensional finite element relocating mesh method can not only guarantee the computation precision, but also improve the calculation efficiency greatly. This provides effective method for simulating construction process and computing temperature field of RCC dam.
