- Abstract
The concrete dam of Chushandian reservoir is made of normal concrete, whose strong constraint area of mass concrete cast in the spring is based on granite rock with elastic modulus of 55GPa.The super-strong baserock makes the temperature control and crack prevention of concrete very difficult. Based on hydration degree algorithm, numerical simulation was applied for a typical non-overflow dam section on a strong constraint area during construction and early working period. Concrete temperature field and stress field were obtained under such a special conditions. Then a reasonable quantitative standards of temperature control and cracking prevention were put forward, which may provide some reference to similar projects.
