Abstract：In the desert area,due to the lack of qualified subgrade materials,the use of geocells with in-situ sand can improve the bearing capacity of the desert road.Also,the economic benefits and the design requirements for the subgrade layer can be achieved.In order to evaluate the reinforcement behavior of geocells,both static and dynamic loading tests are conducted to investigate the bearing capacity and dynamic behaviors.Compared with the unreinforced sand,the geocells significantly improve the performance of the sandy soil used in this study.In the static loading test,with the increasing height of the geocells,the subgrade gains have higher bearing capacity and lower total settlement.Under repeated loading condition,with the increasing height of the geocells,the bearing effect can not be relatively improved.The repeated loading pavement is simulated in the dynamic loading test,and the results show that the design of subgrade reinforced with geocells in desert area can be suggested to have optimization scheme of economic benefits.
