临空面效应下黄土平面应变试验研究
Experiment Study of Plane Strain Considering the Free Surface of Loess
摘要
Abstract
The paper had carried on research on the strength of unsaturated and remolded loess from Yangling of Shaanxi with improved TS-526 true triaxial apparatus under different water moisture,consolidation pressure and dry density including unilateral constraints and bilateral unconstrained test under plane strain conditions. The results show that with the water content increasing,the dry density and consolidation pressure are reduced and the soil strength is lower;the volume change of unilateral constraints keeps in the state of bilateral shear contrac-tion,however,the change of bilateral unconstrained turns from the state of shear contraction to shear militancy;confining constraints have less effect on the axial deformation than the influence to the lateral deformation.关键词
