摘要
通过室内动三轴试验，测试了有色金属铜矿的细粒尾矿动力特性，获得了细粒尾矿在动荷载作用下的动应力与动应变、动应变与动模量及动阻尼比、动孔隙水压与动应力等相关关系，得出动孔隙水压对细粒尾矿动强度的影响有限等结论，对研究细粒尾矿的动力特性作了一些探索。
Through dynamic triaxial test in laboratory, the dynamic characteristics about fine grained tailings of copper ore were tested, and the results which included the relationships of dynamic stress and dynamic strain, dynamic modulus and damping, dynamic stress and dynamic pore hydraulic pressure, are acquired. Results demonstrate that the dynamic pore hydraulic pressure has an limited influence upon the dynamic strength. Exploring work on dynamic characteristics of fine grained tailings is performed.
