| Abstract: | Now the reinforced soil structure is applied widely.But the accidents of destabilizing and collapsing of the reinforced soil engineering especially reinforced soil retaining wall often happen,which has been paid attention to by academe and engineering field.Through the centrifuge model test,the structural characteristics and failure mechanism of the reinforced retaining wall are studied,and the regularities of soil pressure of the graded step-style grid reinforced retaining wall,the distribution for reinforcement tension and wall surface deformation are revealed.The deliverables has further developed the reinforced retaining wall research field,and will provide the reference for project practice. |
