In the process of pouring water tower in the cold area, concrete often produces cracks due to the complex and changeable environmental climate in the area. Therefore, according to the special climate in the area, adopting appropriate temperature control measures is crucial to preventing the cracking of concrete in the water tower. Taking a water tower in a cold area as an engineering example, this paper analyzes the sensitivity of cooling water pipe spacing, water temperature, water length and insulation layer thickness by using three-dimensional finite element simulation software. The maximum temperature in the center of each sensitive factor is analyzed, and the temperature field of the typical elevation of the water intake tower during the entire pouring process is compared, so that the most favorable temperature control measures are optimized. The results of calculating the characteristic points of different parts of concrete under the recommended measures are obtained, and the temperature and temperature stress of different parts of the water tower are obtained when pouring to a typical elevation and long intermittently pouring block. The results meet the needs of the project. The research results serve as a reference for the optimization of similar engineering temperature control measures.
