克孜加尔沥青混凝土心墙坝应力变形研究

Research on Stress and Deformation of Kezijiaer Asphalt Concrete Core Dam

基于E-μ模型,并以克孜加尔沥青混凝土心墙堆石坝为例,采用三维非线性有限元法计算了竣工及蓄水期的应力变形,分析了参数的敏感性,探讨了心墙底部基座的布置型式对心墙应力及变形的影响。结果表明,克孜加尔心墙坝坝体及心墙应力变形均在合理范围内,并获得了心墙参数的取值与坝体应力变形的规律。

Based on E-μ model,stress and deformation of Kezijiaer asphalt concrete core dam in the process of construction and impoundment is simulated by using three-dimensional nonlinear finite method.And the sensitivity of parameters is also analyzed.Then the influence of foundation support layout on stress and deformation of core is discussed.The results show that the stress and deformation of the dam body and core is in reasonable scope,and the parameters value of core and the rules of stress deformation of the dam are obtained.
