摘要
本文采用非线性有限元分析方法,对福建金造桥水电站面板堆石坝的应力变形特性进行了分析研究。文中给出了坝体及面板在施工期和蓄水期的应力、位移分布。计算结果表明:坝体总体变形较小,岸坡约束作用不明显,面板大部分区域在蓄水期沿坝轴线方向和坝坡方向呈双向受压状态,岸坡部分的面板沿坝轴线方向受拉,面板顶部和底部沿坝坡方向受拉。本文提供的计算分析结果除可以为金造桥工程设计、施工提供依据外,对其它类似工程也具有一定的参考价值。
By using non-linear FE analytical method, the stress and deformation properties of the Jinzaoqiao Concrete-Faced Rockfill Dam （CFRD） were analyzed. The stress and deformation of the dam and the concrete face slabs during construction and impoundment periods were presented in this paper. The computation results show that ： the overall deformation of the dam is relatively small and the constraint of abutments to the dam body is not significant. After reservoir impoundment, most past of the concrete face slabs will be subjected to compression stress in both dam axis direction and upstream slope direction, while the slabs near the abutments in dam axis direction and the top slabs and bottom slabs in slope direction will be in tensile situation. The analysis results presented in this paper could provide basis for engineering design and construction of the Jinzaoqiao CFRD, they could also be used as good reference for other similar projects.
