| Abstract: | With the help of the accurate numerical algorithm for pipe cooling temperature field of concrete structures and some characteristic parameters obtained from back analysis of in-situ test result, a comparative analysis was performed of in-situ pipe cooling of sluice piers in the Jiangtang Lake during their construction period. The result shows that the cooling pipe is of obvious effect in heat conduction and temperature reduction, and can be applied to prevention of concrete cracking at the early stage. |

| Keywords: | temperature control and crack prevention pipe cooling sluice numerical simulation |
