| 摘 要： | 采用Duncan-Chang非线性模型对下坂地深覆盖层沥青混凝土心墙坝进行了三维有限元分析,并着重对防渗墙的应力变形进行了分析研究,针对施工过程中防渗墙九种不同的材料级配方案,给出了大坝竣工期、水库蓄水期防渗墙应力和位移随墙体参数变化的规律;优化选择合适的墙体材料配比,为防渗墙墙体的选择提供了理论依据。

| Abstract: | The Duncan-Chang nonlinear constitutive model is used to carry out a 3-D finite element analysis for the Xiabandi asphalt concrete core rockfill dam with deep overburden(147.95m).In the study,the characteristics of stress and displacement in the seepage prevention wall with deep overburden were analyzed, and the rule of stress and displacement change in the seepage prevention wall during engineering completion and water impounding operation period according to eight kinds of characteristic parameters change were given.As well,the paper provided reference for material selection of the seepage prevention wall. |
