摘要
景洪电站地处亚热带,高气温时间长,大坝碾压混凝土施工温控难度高。本文通过对原材料及配合比、混凝土出机口温度控制、运输过程温度控制、浇筑过程的温度控制以及混凝土浇筑后的养护和冷却通水等一系列研究,提出景洪电站高气温条件下大坝碾压混凝土连续施工的综合措施,并在计算和已有经验的基础上给出具体实施方法。
Jinghong hydropower station RCC dam is in the subtropics zone, the high temperature continues very long and the temperature control in dam construction is very difficult. By the research on the raw materials, the mix proportion, the concrete temperature control in outlet, in transport and in placement, the cure and the pest-cooling water, the synthetic measures for RCC dam construction in high temperature and the enforcement methods on basis of the computation and experience of Jinghong hydropower station are presented in this paper.
