Research on Crack Prevention Method for Long Deck of Pump Station

Article Preview

Cracking is a common phenomenon in long concrete structure. But for hydraulic structure it is not permitted because crack will cause heavily seepage and other disaster. Temperature control is an important way to prevent cracking. As for a long deck which has to be constructed in summer, temperature control and crack prevention is a hard work. With the aid of finite element method for temperature field and stress field simulation, research is carried out for a long deck of a pump station. Different measures, such as pipe cooling, surface preservation and pouring temperature control, are tried to control the temperature and stress. The simulation results of different measures composite schemes are analyzed. At last the optimized measures are proposed and its application at site shows it’s successful.
