| 摘 要： | 分别采用邓肯E-B模型和沈珠江双屈服面模型模拟堆石坝体、利用线弹性模型模拟沥青混凝土面板进行有限元变形及应力计算分析,并对两种不同模型在竣工期和蓄水期坝体堆石和面板的应力变形规律进行了比较.结果表明,对外凸反拱曲线型面板堆石坝,邓肯模型计算的面板拉应力较大与实测不符,而弹塑性模型的计算结果则较合理.

| Abstract: | The lower dam of Xilongchi pumped storage power station is a bitumen concrete faced.rockfill dam.For a finite element analysis of deformation and stress calculation,Duncan-Chang E-B model and Shen-Zhujiang's double yield surface model are applied in this paper to simulate the rockfill embankment,and the linear elastic model is applied to simulate asphalt concrete slabs.According to the result of numerical analysis,the distribution discrepancy of stress,deformation of the rockfill and the panel in completion... |
