摘要
针对高面板堆石坝的应力变形特性,分析了堆石体的流变机理,提出了一个能够反映堆石长期变形特性且易于通过反分析方法确定参数的堆石流变模型。研究了公伯峡电站面板堆石坝在不计入堆石流变和计入堆石流变两种情况下的面板坝的应力变形分布范围和形态,以及计入堆石流变后对面板和周边缝所产生的各种影响与程度。
Based on the stress and deformation properties of high face rockfill dam, the rheologic mechanism of rockfill bodies are analyzed. a rheologic model of rockfill is proposed, which can better reflect long-term deformation of the rockfill and is easy to determine parameters through feedback analysis. Analysis is conducted on the stress and deformation of the face rockfill dam of Gongboxia Power Station, including their distribution and pattern with and without calculated rheology, and the influence of rockfill rheologyon faced and surrounding seams.
