| Abstract: | The Duncan-Chang elastic nonlinear constitutive model is used to carry out a 3-D finite element analysis for the asphalt concrete core wall of the dam with deep overburden.The settlement deformation and stress of the dam is influenced by dam foundation and mountain,which is simulated by non-quality foundation methods,the characteristics of stress and deformation problem in the dam and dam foundation with deep overburden is analyzed.Especially,the characteristics of distribution of stress and displacement in the asphalt concrete core wall dam are analyzed,where by provide the theoretical reference to the design of the dam project. |
