摘要
本文论述了采用动三轴仪对大石河尾矿粘性土的动力不排水特性的试验研究成果,研究中,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,并对其动强度修正系数Kα和Kσ进行了探讨.本文还系统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 Kα and Kσ were discussed. A residual strength after cyclic loading was also investigated in detail.
