采用大型三轴仪对球形颗粒散粒体进行了应变式三轴试验。试验结果表明，球形颗粒散粒体应力-应变关系符合理想弹塑性模型，其强度符合Mohr-Coulomb强度理论，体变与轴向应变关系符合线性关系。散粒体的强度和变形特性与其颗粒调整方式有密切关系。

Large scale triaxial shear test on spherical particle coarse aggregate is carried out. The experimental results show that the relationship between stress and strain is in accord with the ideal elastoplastic model, that its strength is consistent with Mohrs strength theory, and that the axial strain and volumetric strain curve is linear. The properties of spherical particle coarse aggregate are close related to the way of particle adjustment.
