| 摘 要： | 已有的研究成果表明堆石流变与颗粒破碎有关,但流变引起的净破碎率和流变之间的关系尚不明确。通过室内大型流变试验,分析了流变引起的颗粒破碎,发现破碎率与最终流变量之间存在线性函数关系,破碎率与轴压之间存在幂函数关系;轴向流变变形与时间之间的关系可以用对数函数表示,相应的流变参数与轴压之间呈良好的线性关系。

| Abstract: | The present study results show that the deformation of rockfill and particle breakage are closely related,but the relationship between the net particle breakage caused by rheology and rheology is not clear.Based on rheological tests,the particle breakage caused by rheology is analyzed.The analysis results show that the relation of the rheological particle breakage to final rheological strain could be expressed by linear function,the relation of the rheological particle breakage to axial pressure could be expressed by power function,the relationship between the axial rheological strain and time could be expressed by logarithmic function,and the relationship between the corresponding rheological parameters and axial pressure is linear. |
