摘要
Abstract
The structure of large-scale vertical flow pump stations is complex,and currently,commercial concrete pouring is generally used.Engineering in the southern region of China is affected by climate,with high pouring temperatures,making temperature control and crack prevention difficult.This paper uses the finite element method to simulate the construction of such pumping stations under summer and winter climates in Guangdong,and obtains temperature and stress envelope diagrams and duration curves for different working conditions.Based on the calculation results,the temperature and stress characteristics of concrete construction under different conditions are summarized and analyzed,and the temperature control and crack prevention schemes for this type of pump station under summer and winter pouring conditions,as well as the temperature control indicators for each pouring layer,are provided.关键词
