Study Of Temperature Crack Control Of Mass Concrete In Raft-foundation

This paper studies the temperature crack of mass concrete in raft-foundation from three aspects which is finite element theoretical analysis, ANSYS numerical simulation and measure of temperature control of mass concrete. First, this paper uses finite element to analyze temperature field of mass concrete and derive corresponding calculative formula. Second, this paper uses ANSYS software to simulate the temperature field of mass concrete in raft-foundation. The result shows that we should take note of the interaction of concrete and soil, when we calculate the temperature field. In addition, it obtains the range of hydration coefficient of mass concrete. In the last, the author applies the measures to direct the building of a real project and calculate the temperature field of it with the methods which are mentioned in the paper. The effect of the construction of project, we can say that the measures of temperature control and ANSYS numerical simulation are effective and feasible.
