| 摘 要： | 推导了高围压下的幂函数流变本构模型在三维有限元分析中的具体算法和实现步骤.根据该流变模型对水布垭面板堆石坝进行了流变分析.结果表明,考虑堆石流变后的坝体沉降有明显的增加,对面板的应力变形状态有较大影响,对于高面板堆石坝,选用合适的流变模型正确模拟堆石体的流变变形及发展规律,对减小面板的裂缝和脱空具有重要意义.

| Abstract: | Based on a rockfill power function creep constitutive model,numerical realization step and detailed algorithm applied to analysis of general FEM is presented for the creep constitutive model.The stress and deformation analysis with consideration of rockfill creep are performed for Shuibuya concrete face rockfill dam.The computation results show that the deformation of dam shows evident increment and the creep has an obvious influence on the deformation and stress of the face.It is very important that the reasonable creep model is adopted and simulated deformation of rockfill correctly and then reasonable construction processes are adopted. |
