Stress-Strain Response of Geocell Reinforced Weathered Phyllite Rock Filling
摘要
Abstract
Using large triaxial test,test and compare the stress-strain curves of weathered phyllite rock and conventional embankment fill gravel soil to meet the specification requirements,analyze the differences between the two;based on the calculation model of the stress-strain response of the geocell reinforced soil and parameter sensitivity,analyze the Duncan's tensile model of elastic constants of the weathered phyllite rock fill,the strength parameter and the tangent modulus of the compartment on the strength of the compartment reinforced weathered phyllite rock.The effect of the Duncan tensor model on the strength of weathered phyllites is analyzed.It is shown that the peak deviatoric stress of the cell-reinforced weathered phyllites can exceed that of gravel,and the equivalent cohesion of the reinforced soil increases with the decrease of the value of the elastic constant k,the increase of the damage ratio of fill Rf,the increase of the angle of internal friction φ,and the increase of the stiffness of the cell strips Mt.关键词
