Study on Lateral compression deformation and constitutive relation of filling body

Lifei Li

Abstract


 In order to study the mechanical behavior of the filling body under compression under deep high stress,Select concentration70%,Gray sand ratio1.:10,Curing age respectively14d, 28D, 56dConfined consolidation experiments under different stress loading levels of classified tailings cemented filling body,The results show that:The axial compression gradually increases with the increase of stress loading level.,Logarithmic function relationship with axial stress;The relationship between axial strain and stress is quadratic function.


Keywords
