摘要
本文采用动三轴仪对大石河尾矿粘性土的动力不排水特性进行了试验研究。研究分析中,考虑了不同应力状态下大石河尾矿粘性土的动力变形、动孔隙水压力的发展和强度的变化,并且对其动强度应力修正系数Kα和Kσ进行了探讨。本文还系统地研究了尾矿粘性土振后应力-应变关系和残余强度特征。
The undrained cyclic behavior of saturated mine slimes was studied in detail by means of dynamic triaxial apparatus.The deformation, pore water pressure and strength were considered under various stress conditions.Dynamic strength correction factors Kαand Kσ were discussed.A residual strength after cyclic loading was investigated in detail.
