Paper Title:
Dynamic Simulation Analysis of Temperature Field and Thermal Stress of Concrete Gravity Dam during Construction Period
  Abstract

The basic theory of temperature field and stress field of concrete and 3D FEM combining with cooling pipe discrete model and iteration method are used to carry out the dynamic simulation analysis of the temperature filed and stress field of a concrete gravity dam of South-to-North Water Diversion Project. The impacts on cracking mechanism of the surface insulation, internal cooling and environmental climate are considered in calculation. The change laws of temperature field and thermal stress with time and their distributions are analyzed, reasonable temperature control measures are put forward for reference. The results show that good effect of temperature control and cracking prevention is achieved, the proposed measures should have great reference significance to the similar concrete dam in future.
