摘要
Abstract
The prototype monitoring data of a concrete gravity dam in Southeast China shows that the dam body and dam foun-dation at the left bank is leaning toward the upstream direction. The qualitative and quantitative analysis results by using different analytical methods such as comprehensive process line contrast and mathematical modelling demonstrate that the leaning phenom-enon is real and the underlying cause is the sedimentation in front of dam. The bedrock of dam foundation at left bank is weak, and the sedimentation year by year in the front of the dam weights the bottom of reservoir, causing the sink of the upstream reser-voir base. The sedimentation phenomenon should be focused, and the effect of the sedimentation on the dam deserves further study.关键词
