... for overall stability than using a single layer with the entire length. By analysing the strain distribution in the foundation, the deformation modes of the embankment reinforced by different numbers of geosynthetic layers were clarified. It was found that increasing the number of geosynthetic layers extended...

...L.-Q. Ding; F.-L. Cui; C.-Z. Xiao In practice, little attention has been paid directly to freeze-thaw (FT) cycles during the design and analysis of geogrid-reinforced soil (GRS) walls due to a lack of relevant literature. This study investigates the pavement vertical deformation (s), panel...

... and the dynamic deformation behaviour of stacked soilbags. The results of monotonic loading tests demonstrate that the ultimate compressive strength and the tangent compression modulus of soilbags tend to relatively stable values of around 0.7 MPa and 6.73 MPa, respectively, when the number of layers exceeds...

... as the frequency and amplitude of loading, the number of reinforcement layers, and the buried depth of the soilbag reinforcement. The results show that soilbags as reinforcement are effective at reducing permanent and resilient deformations of the road subgrade as well as vibrations caused by traffic loads...

... is concentrated on the reinforcement strips, with highest pressure close to the piles, and lowest pressure in the center. Figure 4a shows the load distribution resulting from arching: less reinforcement deformation attracts more load. When there is sufficient differential settlement between subsoil and piles...

The deformation patterns and the relationship between the surface settlement and the differential settlement...

... that without it. The presence of the GCCM constrains the displacement near the slope surface to being along the slope, whereas without the GCCM the slope can deform freely especially in the middle to upper zone of slope area. The results indicate that the GCCM performs well at slope stabilisation. Various...

Horgan Although geogrids and geotextiles have been successfully used for over a quarter of a century to reinforce soil, there are currently no commonly agreed analytical methods to model their deformation behaviour. The serviceability limit state...

Geogrid reinforcement strains, soil specimen deformations, soil suctions and soil temperatures were monitored during the wetting–drying process. Additional strains were observed in the geogrid reinforcement due to a wetting...
