DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Geosythetic-reinforced soil structures have been widely applied in geotechnical engineering. Among them, geocells are applied in enhancing bearing capacities of pavements and footings, reinforcing soft grounds and slopes, and so on. In the practice, the reinforced soil is often regarded as a composite material that is uniform and isotropic. In other words, the effect of the geometry of geocell is ignored, and the behavior of reinforced soil is assumed to be the same irrespective of loading directions. The main objective of this study was to analyze the anisotropic behavior of sand reinforced with geocell by using the finite element software PLAXIS. Verification of the numerical model was based on the results of triaxial compression test on geocell-reinforced-sand samples with appropriately selected material properties, boundary conditions, and strength parameters. 
In the numerical model, the geometry of the geocell was assumed to be composed of two bell-shaped curves. The aspect ratio of single cell was chosen 1.0, and therefore the dimension of a unit of reinforced sand was 0.2m x 0.2m x 0.2m. The unit was then subjected to compressive pressures from three mutually perpendicular directions (x-, y-, z-directions), and the mechanical behaviors of the reinforced sand were obtained accordingly. The deformations of the unit and the reinforcement, as well as the tensile stress distribution in the geocell were examined. To understand the practical applications, the number of unit was increased to form a reinforced layer in soft ground, which was subjected to vertical surcharges at the ground surface.
