摘要
叶巴滩水电站地处青藏高原与川西北高原交接处,其地势高亢,气候寒冷且干燥,多大风且日照时间长,具有长冬无夏、短春秋的特点,属于国内外较为典型的高寒高海拔超长低温期大型水力发电工程。阐述了通过采取全天候连续施工、薄层短间歇施工、气肋膜三种施工技术,实现了大坝混凝土连续、高效、高质量的浇筑施工过程,混凝土外观检查未发现裂缝,温度指标满足设计要求。
The Yebatan Hydropower Project is located at the junction of the Qinghai Tibet Plateau and the Northwest Sichuan Plateau,with high terrain,cold and dry climate,frequent winds,and long sunshine.It has the characteristics of long winter,no summer,and short spring and autumn.It is a typical large-scale water conservancy and power generation project at high cold,high altitude,and ultra-long and low temperature periods both domestically and internationally.By adopting three construction methods:continuous construction throughout the day,thin-layer short-interval construction,and air-ribbed membrane construction,the dam concrete has been continuously,efficiently,and has effectively constructed high quality pouring construction,no cracks found during concrete appearance inspection,and temperature indicators meet design requirements.
