| Abstract: | Based on the simulation algorithms on conditionally merging layers, jointed elem ents and different time steps for different zones, some of problems, such as ele ment meshes, merging layers automatically made, the shape of elements, relayed c alculation problem, reasonable time step and initial temperature for boundaries by impounding ahead of time are studied in this paper, and a practical explanati on is presented by simulating the constructing process and analyzing the tempera ture field for Shapai RCC arch dam during its life span, which could be used as one of the references for designer. |
