On pipe cooling of concrete dams

Pipe cooling is an important measure for temperature control of concrete dams.The temperature field and stress field of concrete dam in the process of pipe cooling is very complex.A survey is given to the analysis method of the temperature field and stress field in concrete dams in the process of pipe cooling,several new methods are given and a best one is proposed.Several factors which have important influences on stress field are analysed and the principles for correct use of pipe cooling in the construction process of concrete dams are given.
