摘要

In this study, the benefit of using geocell reinforcement to improve the bearing capacity of aeolian sand foundations was clearly demonstrated through field plate loading tests. The settlement behaviour of the aeolian sand foundation, vertical earth pressure distribution, and strain in the geocell wall were measured to further understand the mechanisms of the confinement effect, dispersion effect, and stress dissipation of the reinforced aeolian sand foundation. The test results indicated that the bearing capacity of the two- and three-layer geocell reinforcements were 36.8% and 76.9% greater, than that of the unreinforced aeolian sand foundation because the stiffness of the geocell-sand composite increased due to the confinement effect of the geocell, and the vertical earth pressure was effectively dissipated in the second layer of geocell. When loading was applied, the first layer of the geocell played a critical role in stress conversion and dispersion. Then, a calculated method of bearing capacity for multilayer geocell-reinforced soil has been proposed based on Avesani Neto’s method. The proposed method showed a better fit with the experimental results and can provide some useful suggestions for the design of geocell-reinforced foundations.
