Analysis on Causes and Deformation Mechanism of Embankment Disease of a Reinforced Soil Retaining Wall |
| |
| Abstract: | Aimming at the subgrade disease of a reinforced soil retaining wall, the engineering geological mapping, geological drilling, in-situ testing, indoor geotechnical testing and reinforced strip testing were carried out. The damage causes and deformation characteristics are studied, and the deformation mechanism of the reinforced soil retaining wall is analyzed. Through the evaluation from the aspects of appearance, strength of reinforcement band, collapsibility and stability of the subgrade, it provides sufficient basis for the renovation of the reinforced soil retaining wall section. |
