摘要
鉴于蓄泄循环荷载作用下土石坝的基本变形规律对高土石坝的正常运行维护具有重要意义,采用基于广义塑性本构模型的有限元分析方法,分析了高面板堆石坝在蓄泄循环荷载作用下的变形规律。结果表明,在蓄泄过程中坝体的变形逐渐增加并趋于稳定,其变形极值逐渐向坝体上部及上游侧移动。
The basic deformation regularity of earth rockfii1 dam under the "water-draining" cyclic loading is impor- tant for the normal operation and maintenance of high earth rockfill dam. The finite element analysis method based the generalized plastic constitutive model was used to analyze the deformation law of high concrete faced rockfill dam under the "water-draining" cyclic loading. The results show that the dam deformation gradually increases and stabilizes during "water-draining" cycle. The deformation extreme value gradually moves to the upper part and the upstream side of the dam.
