【Abstract】 Due to the huge calculation work in the three dimensional finite element simulation analysis on the RCC dam, this paper puts forward a relocatable grid method based on the "multi layer element" and "growing element". This method not only can greatly reduce element amount and enhance calculation efficiency but also can meticulously simulate the construction process and easily program to gain rapidly the accurate simulation solutions of three dimensional temperature field of dam body. This method will be widely applied to the project calculation.更多还原
