The Simulation And Analysis Of RCC Dam Temperature Stress Fieid Under The Different Temperature Between Summer And Winter

There appeared a dam technology in RCC dam in the world in eighties and nineties of last century.It has advantages of high strength and long service life of ordinary concrete dam and cost savings and short period of RCC dam construction etc.,so this dam technology was quickly adopted by world community dam engineers.But many operators of roller compacted concrete dam cracks appeared,scientists from various countries made study from all aspects to solve this problem,and show that the ambient temperature and temperature stress load of dam itself is the main reason leading to the destruction of the dam.This study is the use of ANSYS in this computer software on the basis of previous studies for the dam JIANGYA non-overflow section(# 8)and the overflow section(# 5)temperature field,temperature stress and structure research and analysis and other aspects.Select a different season and water level to form different combinations of temperature load.By studying,they got the results of dam stress and displacement under different temperature load.In recent years,JIANGYA Hydropower drizzle water basin,Precipitation is unstable,storms and droughts are frequent.Combine results of this study and the external environment of dam in recent years to control dam temperature and prevent crack,so complete the dam flood control,power generation,water storage and other tasks better.This is the practical significance of this research.
