运用PFC3D模拟砂土细观破碎是离散元中比较常用的方法,国内外很多研究者研究了砂土在一维压缩和三轴实验下的细观破碎模拟。很多学者对砂土破碎准则做出了很多论证,本文将论证其中的一种,得到砂土的e-logσ曲线看齐定性规律是否符合实验趋势。
The use of PFC3D to simulate the meso-crushing of sand is a commonly used method in discrete elements. Many researchers at home and abroad have studied the meso-fractured simulation of sand under one-dimensional and triaxial tests. Many scholars have made a lot of arguments about sand crushing criteria. This paper will demonstrate one of them. Whether the e-logσ curves of sand meet the experimental results is consistent with the qualitative law.
