| 中文摘要: |
| 根据碾压混凝土拱坝的结构特性与碾压混凝土材料的破坏特征，以Sidoroff各向异性损伤理论为基础，建立了碾压混凝土正交异性损伤本构模型；基于正交异性损伤模型的损伤传递方式，导出了碾压混凝土材料的损伤演化方程。以碾压混凝土在复杂应力下的试验资料，对碾压混凝土正交异性损伤本构模型进行了验证。 |
| 英文摘要: |
| According to the structural characteristics and material damage features of RCC arch dam, the orthotropic damage constitutive model is established based upon the sidoroff's damage theory for an isotropic material. Considering the damage transfer mode of this model, a genetic equation describing the damage of RCC in all direction is derived. The parameters in the genetic equation are determined by the experimental results for RCC specimen under complicated stess conditions. |
