| 摘 要： | 虽然高粉煤灰掺量使得碾压混凝土水化热较低,但由于采用通仓连续碾压的施工方式,使得碾压混凝土高坝的温度裂缝问题依然十分突出。本文通过分析碾压混凝土温控防裂的特点和裂缝的分类及原因,针对性的研究总结了温控防裂的措施,为碾压混凝土坝的设计施工和防裂提供参考。

| Abstract: | In the recent years,roll compress concrete dams are developed rapidly.The RCC which contains higher ratio of fly ash makes heat occurred by water and cement mix lower,but the construction of continuing roll compress make the temperature cracks always happened in the higher RCC dam.Through analysis of the feature of temperature control against cracks in roll compress concrete,of the sort and cause,this paper researches and summarizes the temperature control crack prevention measures,which provides the reference for the design and construction of RCC dam. |
