Abstract
Water conservancy and hydropower project is an important infrastructure project in China,which plays a vital role in the development of national economy and the maintenance of social stability,so its engineering quality is particularly important.The construction of water conservancy project will involve the rolling construction of mass concrete.Due to the influence of temperature or process factors,the risk of structural cracks will be increased,which will threaten the safety of the dam.Therefore,it is of great practical significance to carry out the finite element analysis of temperature control simulation of roller compacted concrete dam section.Taking the dam section of Huangjinxia Pumping Station as the research object,the temperature field and temperature stress of the concrete construction process are simulated and calculated,and the spatial and temporal distribution and variation of the structural temperature field and temperature stress are analyzed.According to the analysis results,it is proposed to reasonably control the temperature,adopt water cooling,reduce the peak temperature,reduce the risk of cracking,and improve the construction quality.关键词
