【摘要】 通过数值仿真手段,对云南澜沧江古水电站面板堆石坝进行应力变形计算,并针对坝体的位移、应力、应力水平以及面板的挠度变形进行了分析研究,并针对所拟定的三组计算参数方案进行敏感性分析。结果表明:古水面板堆石坝坝体及面板的应力变形分布符合一般规律,坝体堆石料的变形及面板的挠度变形均较为适中,坝料抗剪具有较高的安全裕度,总体来说,坝体及面板的应力变形在可控范围之内。更多还原

【Abstract】 By means of numerical simulation the paper carried out the stress deformation calculation of the concrete face rock-fill dam of Gushui Hydropower Project in Yunnan Province,made analysis and study according to displacement,stress and stress level of the dam body and deflection deformation of the concrete face slab and conducted sensibility analysis according to the proposed 3 groups of calculation parameters.The results show that the stress deformation distribution of Gushui concrete face rock-fill dam body and concrete face slab conforms to the general laws,the deformation of the dam body rock-fill material and the deflection deformation of the concrete face are both moderate and the shear of the dam materials allows a large margin of safety.Taken as a whole,the stress deformation of either the dam body or the concrete face is controllable.更多还原
