The cyclic load of overload vehicles will cause uneven deformation of the roadbed, leading to serious safety accidents. Geo-synthetics can effectively restrict the roadbed as a type of reinforcement. However, it is not clear how to arrange geo-synthetics for a good balance between the economic benefits and sufficient reinforcement. A series of centrifuge model tests of geo-synthetics reinforced roadbed are carried out under the cyclic loads. The deformation and reinforcement effect are investigated by considering the different geo-synthetics spacing. The results show that geo-synthetics effectively restricts the roadbed deformation. The reinforcement effect of geo-synthetics decreases with the increase of depth along the loading center. The geo-synthetics reinforcement effect is enhanced by decreasing the geo-synthetics spacing. The cyclic loads only induce deformation within a limited zone in the roadbed. As the geo-synthetics spacing decreases, the depth of the deformation zone decreases while the horizontal width increases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
