本世纪以来,世界各国在水电工程方面有了较大的发展.有些国家由于所处的地理环境,针对水电建设的特点,在混凝土坝冬季施工方面有不少经验和教训可供借鉴.我国的一些大坝修建在寒冷和高寒地带,对混凝土坝的施工提出了特殊的保温要求.本文主要针对龙羊峡重力拱坝冬季施工拟采用的暖棚保温方案,收集整理了一些国内外资料,供有关方面参考.
Since the beginning of this century, all countries in the world have made great progress in hydropower engineering. Some countries have many experiences and lessons in winter construction of concrete dams due to their geographical environment and the characteristics of hydropower construction. Some dams are built in the cold and alpine areas and put forward special insulation requirements for the construction of concrete dams.This paper mainly aims at the warm insulation plan to be adopted in winter construction of Longyangxia gravity arch dam and collects some domestic and foreign materials for For reference.
