公伯峡水电站面板堆石坝应力应变计算

Stress and Strain Calculat ions of Gongboxia Hydroelectric Station

公伯峡水电站面板堆石坝经过多次的应力、应变计算,对坝体填筑临时渡汛断面、坝体平起填筑、面板一次施工和面板分期施工分别做了计算,初步揭示了不同施工方案对坝体及面板应力、应变的影响。通过有限元计算分析,可以看出公伯峡水电站面板堆石坝是安全、可靠的。

Stress and strain calculations are made of concrete face rockfill (CFRD) dam for Gongboxia Hydroelectric Station. The calculations are also carried out for temporary embankment fill section during flood season, equalized rising of embankment fill in full section, continuous construction of concrete face slab in one time and in stages respectively, which primarily indicates that different construction schemes have effects on the dam body and stress-strain of concrete face slab. By finite element analysis and calculation, it is believed that CFRD is safe and reliable.
