摘要：A roller compacted concrete gravity dam is located in cold region,in its construction,the long block pouring method is adopted without longitudinal joints and with intermittent construction in overwintering,which would increase the difficulty of temperature control and crack control.In order to have a deep understand of the temperature control measures and effect of the project,the water retaining dam section is selected as the study object in this article,and three schemes are adopted for 3-D finite element simulation analysis.Compared with the results of the three schemes,it can be con-cluded that the temperature control measures such as insulation and cooling water pipes have important significance to im-prove the dam temperature distribution,lower the temperature stress and prevent the dam cracks.Also,the results of this article have important guiding significance in the structural design and construction of the project and similar ones.
