摘要
岩滩水电站大坝经过十多年的运行,由于汛期泄水振动及自然降雨、水流冲刷等原因,溢流坝弧形闸门的8个支墩表面均有不同程度的裂缝,对大坝安全泄洪构成威胁。文章介绍通过对存在的裂缝进行检查及处理,从而达到消除隐患的目的。
Since the dam of Yantan Hydropower Station was put into use for more than a decade,surface cracks have been found on eight piers of overflow dam＇s radial gate due to vibration as a result of water discharge during flood period and rain scouring.Through crack detection and treatment,risks are removed.
