摘要
针对天生桥一级水电站钢筋混凝土面板堆石坝投运以来,钢筋混凝土面板曾发生过多次挤压破坏的问题。通过对1999~2013年监测数据统计,分析钢筋混凝土面板应力应变分布规律、发展趋势和增长速率,探讨其挤压破损机理,为大坝面板破损修补提供参考依据,确保大坝安全运行。
The reinforced concrete face slab rockfill dam of Tianshengqiao I Hydropower Station has seen crushingdamage of face slab several times since it was put into operation. Based on the monitoring records within the periodof 1999~2013, the author analyzed the distribution rule, development trend and growth rate of stress and strain atthe reinforced concrete face slab, probed into the crushing damage mechanism, so as to provide reference basis forthe damaged face slab repair and guarantee main dam safe operation.
