| 摘 要： | 以在建的大华桥碾压混凝土重力坝为例,采用ABAQUS软件中的混凝土损伤塑性本构模型,模拟了大坝在静力荷载与地震荷载下的工作性态,对比分析了坝体材料的线性与非线性对大坝应力位移的影响及坝体在地震作用下可能出现的损伤破坏区及其规律.验证结果表明,坝体材料采用非线性比线性更能反映实际坝体应力分布与位移规律及坝体的损伤破坏区,为混凝土重力坝的震害研究提供了参考依据.

| Abstract: | Taking Dahuaqiao RCC gravity dam in construction for an example, concrete damage plasticity constitutive model in ABAQUS software is used to simulate dam performance under the static load and seismic load. And the influence of linear and nonlinear materials on dam stress and displacement is analyzed. Then it discusses the rule of the dam damaged areas under action of earthquake. Test results show that the non-linear materials is better than the linear to reflect the actual laws of the dam stress distribution and damage area, which provides reference for study of concrete gravity dam on earthquake damage. |
