Study on Hydrated Heat Temperature Field of Thick Raft Concrete Foundation Using FEM Analysis

Abstract:

Based on a wind turbine thick concrete raft foundation for the engineering background, through the adiabatic temperature rise test, the datum of the hydration heat of concrete are obtained; and concrete solidification temperature field numerical simulation and analysis are conducted by finite element analysis software ANSYS; by means of the temperature sensor measurement systems, the foundation concrete pouring process variation of the temperature field is obtained by real-time monitoring. Studies show that: the temperature rise inside the concrete points has the same trend, but the peak and the peak of the age are different. The maximum temperature inside the concrete is mostly shown in the initial 3-5d of concreting; temperature gradient along the thickness direction of the foundation is obvious; massive concrete is significantly affected by the outside temperature.
