## 1 Introduction  
Deserts account for 20% of the Earth's total land area [1; 2; 3]. Desert highways can greatly reduce detours, save energy, and reduce carbon emissions. In desert regions, there is an inexhaustible supply of aeolian sand that is too fine and non-cohesive to be employed as highway filler in the upper roadbed of highways [4]. The traditional upper roadbed is filled with gravelly soil. However, the gravelly soil is tiny and unevenly distributed in desert areas. The long transportation distance leads to high engineering costs. Therefore, using aeolian sand to pave the upper roadbed is one of the most important research topics for reducing the cost of desert highways [5]. DHT soil coagulant and cement were utilized to cure wind and sand [6]. When the amount of aeolian sand incorporated is about 68%, the mix's compressive strength meets the specifications required for highway strength. Enzyme-induced carbonate precipitation and polyvinyl alcohol enhanced the cementation of aeolian sand particles. The unconfined compressive strength, wind erosion resistance, water erosion resistance, and surface strength of aeolian sand were improved [7]. However, the cementing solution releases ammonia to pollute the environment. Reinforcing the aeolian sand with glass fiber and cement strengthened the bond between the sand particles [8]. However, the particles were prone to slip between them. Previous studies have explored different materials for curing aeolian sand, thus meeting the design requirements for highway roadbeds. However,the proposed method of aeolian sand has little admixture, pollutes the environment, and is immature, and there are few efficient methods to lower the cost of desert highway construction projects. Geosynthetic materials are widely used in geotechnical engineering [9]. The enclosed geocell has a lateral restraint effect on the soil it reinforces, stress homogenization as the membrane effect, as well as a friction effect due to the pressure between the cell material and the soil. There is a substantial difference between the elastic modulus of the geocell and that of the material contained within it. Under traffic load, the contact surface of the geocell and the filler have the propensity to slip comparatively, thus generating friction. The friction depends on the energy transmitted down from above, as demonstrated through model tests [10]. Geocell compartments can improve soft soils, according to a survey study [11]. Figure 1 shows the reinforcement mechanism of geocell. Using numerical simulations and laboratory measurements, the pressure-spreading impact of geocells was established [12]. Through model studies, geocells raised the ultimate bearing capacity of aeolian sand layers by a factor of four. Moreover, the experimental studies through three-dimensional modeling demonstrate that geocells spread the load over a larger region beneath the structural layer [13; 14]. A significant triaxial test indicated that geocell reinforcement of dense sandy soil is significantly more successful than that of loose sandy soil [15]. Geocells could stabilize circulation resistance to resistance to sudden destruction in excess of static capacity [16]. Geocells can lower displacement amplitude by 61% when used to reinforce aeolian sand [17]. Through static triaxial testing, dynamic triaxial tests, model tests, and numerical simulations, previous research has analyzed the performance of geocell-reinforced wind-deposited sand. Data such as stress-strain,

The study has significant scientific relevance; however, it does not account for actual traffic volumes. Essential metrics for evaluating the reinforcing effect are the dynamic characteristics of the roadbed under actual dynamic wheel load [18; 19]. The purpose of this paper is to study the vibration characteristics of geocell-reinforced aeolian sand roadbeds under the actual moving wheel load.
