摘要提出了基于cT 扫描技术和PFc 三维颗粒流程序建立含砾滑带土三维建模方法. 首先, 通过cT
扫描技术获得含砾滑带土三轴试样的一系列二维切片图像, 采用二值化和砾石边界识别方法 …

Angle of repose is an important macroscopic feature in characterising the interactions within
an assembly of particles. In order to accurately predict the angle of repose of the particle …

Three-dimensional scanning technology was used to construct the database of natural block
stone shapes with different particle sizes. On the basis of Particle Flow Code 3D, a discrete …

We used CT scanning and PFC 3D to establish the gravel-bearing slip soil model in three
dimensions. Firstly, we obtained the point cloud data of the gravels through binarization …

The macro-and micro-physical properties of cement-stabilized steel slag (CSS) base
materials in a highway project were studied. A discrete element model of CSS with a real …

Performance of unbound paving mixture is highly dependent on the compaction process.
The mixture compaction ability may be impacted by various factors, such as aggregate …

摘要为了准确确定不规则, 分散的农业物料籽粒的休止角, 需要建立与真实物料形状高度相似的
籽粒仿真模型, 并采用数值方法对物料的堆积特性进行仿真研究. 本研究以“甬尤15 号” …
