“…Costa et al [16] investigated the time dependent deformations in geotextile reinforced soil walls. Deformations of geogrid reinforced soil walls through centrifuge model tests at constant gravity under the effects of molding water content and stiffness of the geogrid were presented by Balakrishnan and Viswanadham [17]. Provision of stiffer geogrid reinforced soil walls reduced problems due to the marginal backfills as stated in study.…”

Changing the natural conditions of soil creates unexpected stress increments in slope stability projects, which are required high amount of soil excavation near the highways and railways or braced cut systems. Some safety problems can occur during this application under different loading cases. In addition, slope stability design requires economical solutions. Slope-supporting structures should be designed with most effective solution according to these signified requirements. A slope stability problem considering deep excavations in front of the reinforced soils are studied within this study in all its parts, after an extensive review of the literature. Geotextile (GT), geogrid (GG) and steel strip (SS) reinforcements are used to increase the stability conditions of slope during both experimental procedure and modelling process with Plaxis software. Each reinforcement type provided the bearing capacity enhancement and showed that unique displacement behavior. Therefore, most effective reinforcement member can be chosen in design procedure and construction phase in the site according to the bearing capacity and displacement requirements according to presented values.

Abstract. Most of the proposed methods for obtaining the free vibration natural frequency of the retaining wall assume the behavior of the wall in the two-dimensional domain, and they are not able to express the three-dimensional behavior of these structures in a satisfying manner. Moreover, the effect of damping has not yet been considered in analytical study. In this paper, the plate theory and Galerkin method is employed to analyze the free vibration of a wall-reinforcement-soil system in the three dimensional domain and survey the effect of damping on the natural frequency of a retaining wall. So, the retaining wall is modeled as a clamped-free plate and the stiffness of the soil and reinforcements existing behind the wall are modeled as a set of springs and the damping effect of the system is modeled by a set of dampers located at the back of the Retaining wall and attached to it. The results of the proposed model are compared with both the results of the other researchers and the ones from finite element method (FEM). They are also compared with the results of a full-scale experiment and it shows a good agreement. The proposed method which uses the plate theory, also yields the free vibration natural frequencies of the wall's extensional modes with an acceptable accuracy. Finally, the effect of tensile and compressive behaviors of the soil and the reinforcements on the fundamental frequency of a reinforced retaining wall is studied.Keywords: reinforced retaining wall, reinforcement, 3D vibration, analytical method, damping ratio, mode shape.

“…The bearing and energy adsorption capacities are increased with the geogrid reinforcement [3]. The problems caused by the marginal backfills can be reduced by the providing stiffer geogrid as soil reinforcement [6]. The strength in bonding between the backfill and geogrid is reduced by large sized particles present in the backfill [8].…”

A type of geosynthetic material named geogrid plays a pivotal role in the behaviour of concrete by implementing them as an additional reinforcement. Geogrids have good tensile strength as they are formed by the reticulation of tensile elements with an opening of an ample size which allows interlock with the nearby fill materials. These grids are flexible mesh which is highly effective and enhances the life of the structure. The prime constituents of geogrid are polyester, high-density polyethylene, and polypropylene. More often, in the field of civil engineering,uni-axial, bi-axial and tri-axial geogrids are used. As the cost and duration of construction are nominal, geogrids can be optedfor cost-effective and resilient construction. They are frequently used as reinforcement and for stabilization in structures like retaining walls, pavements, foundations, slopes, and embankments. The geogrids are employed in various construction which results in sustainable development. Thus, this paper discusses diverse studies that have been carried out by using different types of geogrids for various purposes by different research scholars
