Temperature Measurement and Data Analysis of the Roller Compected Concrete Dam

Abstract:

Prototype observation of the concrete dam is an important and effective measure to master the operating condition of dams. Analysis of changes of concrete temperature for dams is the basis of studying the safety of dam operation. By analyzing the raw monitoring data of temperature of a RCC dam, this paper researches the changing process of concrete temperature and internal concrete partitions temperature variation of dams. It also draws the temperature field of the dam concrete. The results show that the isothermals of downstream side parallel with the surface of the downstream dam, and the isothermals of upstream side intersect with the dam. Isothermals which are near to the dam’s surface are close. This suggests that temperature gradient there is large. There is a high temperature nucleus and two low temperature nucleuses in the temperature field of the dam in summer, while in winter there is only one high temperature nucleus. So it suggests that the temperature field in summer is more complex.
