摘要
为了研究块体形状对岩石黏结颗粒模型(BPM)力学特性的影响,分别选取随机多边形块体和随机三角形块体建立了Voronoi-BPM和Trigon-BPM模型,进行了岩石的单轴压缩、单轴拉伸和直剪数值试验。分别从破坏形式和宏-细观力学参数2个方面,分析了块体形状对岩石细观离散元模型力学特性的影响。
In order to study the influence of block shape on mechanical properties of the rock bonded particl model（BPM）, selected separately random polygonal blocks and random triagular blocks, Voronoi- BPM and Trigon-BPM models are established based on UDEC, and uniaxial compression test, uniaxial tensile test, direct shear test are simulated. Block geometry effect on the mechanical behavior of microscope rock discrete element model is analyzed based on failure pattern and marco- and micro- mechanical parameters.
