中文摘要:
      为研究堆石料填筑标准对于狭窄河谷高面板堆石坝应力变形的影响规律,本文运用三维有限元法,以某高面板堆石坝工程为例,进行了堆石料不同填筑标准下的大坝应力变形特性的对比研究。结果表明:随着堆石料填筑标准的提高,坝体和面板的应力变形均基本呈现单调递减的变化规律,且堆石料填筑标准对坝体和面板应力变形的影响存在一个明显的“拐点”,如本文工程实例的主堆石料干密度影响“拐点”为2.16 g/cm3。因此,通过提高堆石料填筑标准,可以明显改善狭窄河谷中高面板堆石坝的应力变形状况,但应注意堆石料填筑标准对大坝应力变形的影响存在“拐点”这一特性。
英文摘要:
      In order to analyze the influence law of rockfill standard on stress deformation of the narrow valley high CFRD, the paper took a narrow valley high CFRD project for example and conducted a comparative study of stress and deformation properties of rockfill dam under different compaction standards based on the three-dimensional finite element method.The results show that as the improvement of rockfill standard, the stress and deformation of panel are gradually decreased. And there is an obvious “turning point” for the impact of rockfill dam compaction standard on the stress and deformation of the panel. The “turning point” of main rockfill dry density is 2.16 g/cm3. Therefore,with the improvement of rockfill standard, we the stress and deformation conditions of the narrow valley high rockfill dam can be significantly improved. But it should be paid attention that there is the “turning point” which exists in the impact of the rockfill dam compaction standard on its stress and deformation.
