摘要

简要介绍了公伯峡水电站混凝土面板堆石坝坝内堆石料流变试验结果和流变计算模型。采用三维有限单元法对公伯峡水电站混凝土面板坝进行了模拟计算

对比了考虑堆石料流变和不考虑流变的计算结果

分析研究了堆石料流变特性对坝体变形以及对混凝土面板应力变形和周边缝位移的影响。

Abstract

The rheological test results and the rheological model of rockfills in Gongboxia Concrete Faced Rockfill Dam（CFRD）were introduced summarily. The 3-D finite element method was used to calculated the stress-strain of Gongboxia CFRD. By contrasting the results from taking into account the rheological effects with that from without taking account of rheological effects of rockfills

the influence of rheological behaviors of rockfills on deformations in dam

on stress and deformation of face slab and on the deformation of the peripheral joint were analyzed and studied.
