溧阳抽水蓄能电站上水库交通桥连续刚构梁施工技术

Construction Technology of Continuous Rigid Frame Beam for Upper Reservoir Traffic Bridge of Liyang Pumped-storage Power Station

溧阳抽水蓄能电站上水库两座交通桥为连续刚构梁,其连接进出水塔和库岸及(1)号副坝的环库路,针对其施工难点,探索出了一套适合薄壁双肢高墩的连续刚构桥梁施工技术,取得了良好的效果。

The two traffic bridges in the upper reservoir of Liyang Pumped-storage Power Station are continuous rigid frame beams, which connect two intake towers to reservoir bank and circular reservoir road of No. 1 auxiliary dam. Based on the analyses on construction difficulties, a set of continuous rigid frame bridge construction technology suitable for thin-walled double-limb high pier is explored, which has obtained good achievements.
