| 摘 要： | 综合已有的研究成果,从压缩、剪胀和强度三方面分析颗粒破碎对堆石料应力-应变特性的影响。基于堆石料的变形和强度特性,引入新的硬化参数H,并推导出相应的屈服函数表达式,进而提出一个能够考虑堆石料颗粒破碎影响的弹-塑性本构模型。利用基于空间滑动面准则（SMP准则）的变换应力方法将模型进行三维化,并参照某堆石料大三轴试验结果对...

| Abstract: | Integrating existing research results,such as compressed,dilatancy,and strength,the influence produced by particle breaking on stress-strain characteristic of rockfill was analyzed.Based on the deformation and strength characteristics of rockfill,a new hardening parameters H was introduced,and corresponding yield function was derived,then a elastic-plastic constitutive model was proposed which could consider the impact of rockfill particle breaking.Based on the transformation stress method on SMP criterion ... |
