Application of Temperature Control for Crack Prevention of Large Volume Concrete under the Pouring and Reinforcement of Reservoir Main Dam
During the large volume pouring process of dam concrete,due to the heat release from cement hydration,an uneven temperature gradient stress field is easily formed inside the concrete,which increases the risk of concrete cracking.This paper takes the main dam reinforcement project of Chiao Reservoir as the research background,and proposes a cooling water circulation system for temperature control and crack prevention in the construction of large volume concrete pouring.A temperature field function measurement and control system combined with a large volume concrete cooling and temperature measurement integrated system achieves the goal of precision and safety guidance for temperature control construction.
