摘要
Abstract
With the continuous improvement and development of domestic dam construction technology,RCC dams have become a relatively unknown dam type for project builders due to their excellent characteristics and convenient construction methods.Temperature control and anti-cracking measures during the construction period have also been highly valued.Pay attention to.Arranging cooling water pipes to pass in cooling water for cooling is the main temperature control measure during the construction period of concrete dams.Its layout has a significant impact on the temperature field of the concrete in the dam body.By establishing a three-dimensional finite element model of the dam body,riverbed and dam section,simulation calculations of 6m Temperature fields of different layouts of concrete cooling water pipes in the dam during the construction process.The results show that the narrower spacing of the cooling water pipes can effectively reduce the temperature inside the RCC dam and make the maximum temperature inside the dam reach the range required by the design.It can also reduce the temperature stress of the dam body,play a significant role in temperature control and crack prevention of RCC arch dams,and provide a certain reference basis for the design and construction of similar projects.关键词
