梅溪水库面板堆石坝原型观测资料反馈分析及大坝变形预报模型

Back analysis of observation data of Meixi CFRD and stud y on prediction model for dam deformation

摘要: 根据梅溪水库面板堆石坝施工期和水库蓄水初期坝体的原型观测资料，对坝体应力变形分析所用的坝料计算参数进行了反馈分析，得出了坝体堆石料及坝基覆盖层的弹塑性应力变形计算参数。从统计模型的角度出发，研究了坝体变形长期预报模型，建立了考虑填筑分量和时效耦合作用的预报模型。

Abstract: Based on the observation data during the construction stage and filling stage of Meixi CFRD, back analysis was fulfilled to calculate the parameters of the rockfills and river deposits. By means of statistical model, the long term prediction model of dam deformation was studied and a model considered the coupled action of filled rock and time effect was developed.
