摘要:

某水电站建设过程中一期面板出现了结构性破坏和裂缝,对面板破坏情况进行检查并分析破坏原因,根据混凝土面板结构受力特点和当地实际情况,提出了面板修复处理措施。混凝土面板经修复处理后,变形已稳定,渗漏量控制在允许范围内。最后总结了面板修复施工过程中需要注意的问题,可为类似混凝土面板堆石坝的建设提供参考。

Abstract:

In the first phase construction process of a certain hydropower station, structural damage and cracks appeared on the face. In this paper, the face destruction was checked and the damage reasons were analyzed firstly. After that, some face restoring treatments were proposed according to the stress features of concrete face and local actual conditions. After the restoring, the deformation of concrete face became stable and the leakage was controlled within the permissible range. At last, this paper summarized the problems that need attention in face restoring process and provided a reference for similar construction project of concrete face rockfill dam.
