| Abstract: | Embankment widening technology by reinforcement slope without more land is presented considering the characteristics of Fo-Kai Expressway.Centrifuge model tests are carried out for verification of the design scheme of Fo-Kai Expressway extension project.The results show that the widening embankment reinforcement technology without more land is safe and reliable.A comparison of deformation characteristics between unreinforced and reinforced models for the widening embankment is made,the effect of geogrid spacing on deformation of the widening embankment is studied. |
