| 摘 要： | 水库先期蓄水和后期蓄水对大坝的应力变形有不同的影响。采用邓肯-张E-B模型对冶勒水电站堆石坝进行三维有限元建模,结合不同坝体材料的计算参数,在先期蓄水和后期蓄水条件下,拟定两种计算方案,对沥青混凝土堆石坝在竣工工况和正常蓄水位工况下的应力变形进行了三维有限元分析,并从应力变形角度对其安全性进行了初步评价。通过计算分析和比较,这两种蓄水方式下大坝的应力变形均符合堆石坝的一般分布规律,且量值在合理的范围内。 |

| Abstract: | Early and late impoundment ways have different effects on stress-deformation of reservoir dam.By adopting Duncan-Chang E-B model,we established 3D finite element model for asphalt concrete core rockfill dam in Yele Hydropower Station.Combining calculation parameters of different materials of dam,we worked out two numerical procedures under the conditions of early and late water storage ways.Furthermore,we carried out 3D finite element analysis on stress-deformation of the asphalt concrete core rockfill dam ... |
| Keywords: | finite element impoundment ways stress-deformation Duncan-Chang E-B model |
