Abstrait:

The deep hole area is a key part of the dam during the construction period, and its temperature field and stress field changes are the focus of the current research on temperature control and crack prevention in the deep hole area. Based on the traditional three-stage and nine-stage temperature control standard, this paper uses three-dimensional finite element temperature stress simulation analysis to study the three major research ideas of shortening the medium-term cooling, shortening the second-stage cooling, and shortening the two at the same time. The concrete silo with a relatively lagging temperature control phase reaches the arching temperature at the same time. The simulation results show that the three temperature control measures can not only keep the stress in the area within a safe range, but also effectively shorten the construction period, providing new ideas for temperature control measures in the deep hole area of the arch dam.
