丰满重建工程蓄水初期大坝工作性态分析

Analysis of dam performance of Fengman Reconstruction Project during initial impoundment period

根据大坝安全监测资料,对丰满重建工程蓄水初期坝体及坝基的变形、渗流、应力等的时空分布规律进行了分析,进而对大坝整体工作性态进行了评价。监测成果表明:坝体及坝基变形符合重力坝的一般变化规律,变形量值在合理范围内,坝基帷幕防渗总体效果良好,坝踵坝趾均处于受压状态。大坝总体工作性态正常。

According to the monitoring data of the dam of the Fengman Reconstruction Project,the temporal and spatial distribution of deformation,seepage,and stress of the dam and foundation at the initial impoundment of water storage are analyzed,and then the overall performance of the dam is evaluated.The monitoring results showed that the deformation of the dam and foundation conforms to the general laws of the gravity dams.The dam deformation is within a reasonable range.The overall anti-seepage effect of dam foundation curtain is good.The dam heel and toe are all under compression.on the whole,the dam performance is normal.
