摘要
黄金坪水电站大坝为沥青混凝土心墙堆石坝,坝基防渗墙与沥青混凝土心墙采用坝基廊道进行连接。2014年11月康定地震后,坝基廊道内部边墙、顶拱及底板存在大量裂缝,伴有渗水、泛碱现象,且发展变化趋势较大。本文通过复核坝基廊道结构安全性,结合工程施工实际及施工监测情况,对裂缝成因进行了分析。分析成果能够为类似工程提供参考借鉴。
The dam of Huangjinping Hydropower Station is a rockfill dam with asphalt concrete core wall.The dam foundation gallery is used to connect the impervious wall and asphalt concrete core wall.After the Kangding earthquake in November 2014,it was found that there were a large number of cracks in the inner side wall,top arch and bottom plate of the dam foundation gallery,accompanied by water seepage and efflorescence,and the development trend was large.By reviewing the structural safety of dam foundation gallery,combining with the actual construction and construction monitoring,the causes of cracks are analyzed.The study results can provide reference for similar projects.
