摘要
Abstract
Temperature control requirements for the concrete dam that located at latitude alpine region are strict and challenge,for a great climate change over the year and the influence of complex climate such as high temperature,freezing cold,dry and too much evaporation,and so on. The calculation method of temperature stress control,safety factor of crack-resistance and the determination of temperature control criteria,the compre-hensive measures application of temperature control,early and post concrete surface conservation and protection and other aspects of technology were researched and applied in the actual project. The results show that the maximum temperature and the maximum temperature difference of concrete dam construction meet the design requirements with only a small amount of surface cracks appeared in partial area and without greater danger pene-trating cracks.关键词
