摘要

堆石料具有显著的颗粒破碎和三维形状特性

该特性对材料的整体强度和变形特性的影响不容忽视。为剥离颗粒破碎和三维形状特性对堆石料强度和变形特性的影响

采用玻璃球来近似模拟堆石料

基于中型三轴仪器分析了颗粒组构对强度和变形特性的影响。结果表明:在颗粒破碎不明显的工况下

玻璃球能够近似模拟堆石料的强度和变形特征

颗粒破碎对试样的强度影响要低于其对体积应变的影响;材料的峰值强度随着颗粒直径的增大而增大

体积应变随着颗粒直径的增大而减小;在孔隙比相近的情况下

颗粒级配的变化对材料的强度影响较小

对体积应变影响较大

小颗粒掺入有助于改善级配和控制剪胀变形。

Abstract

Rockfill has significant characteristics of particle breakage and 3Dshape

the influence of these characteristics on material’s strength and deformation characteristics can not be ignored.In order to isolate the influence of particle breakage and 3Dshape characteristics on rockfill’s strength and deformation characteristics

crystal ball was used to simulate rockfill

and analysis of the influence of particle fabric on strength and deformation characteristics was carried out on the basis of medium-sized triaxial apparatus.The test results show that:crystal ball can approximately simulate the strength and deformation characteristics of rockfill in the condition of no particle breakage.Particle breakage has less influence on strength than volume strain;Peak strength increases with the increase of particle diameter

and volume strain decreases with the increase of particle diameter;In the condition of similar void ratio

the change of particle gradation has little influence on strength

but it influences obviously on volume strain

and small particle incorporation helps to optimize the gradation and control the dilatancy deformation.
