“…It should be noted that most factor of safety analysis of slopes are based on either the limit equilibrium or numerical methods. As a result, some investigators have validated their works with published numerical data [26][27][28]. Therefore, the validity of the numerical simulations utilized in this study has been verified by using the finite element method to predict the load-settlement behaviour of a footing resting on an unreinforced slope as reported by Gill et al [29] as well as the failure surface and associated factor of safety of a geotextile-reinforced slope from a centrifuge test data reported by Zornberg et al [30,31].…”

In several field situations, especially in the hilly terrains, the construction of footings on slopes becomes essential. The factor of safety of a slope supporting a loaded footing on the crest is dependent on the position of the footing from the crest edge. Most studies in the past have focused on analysing the bearing capacity and settlement behaviour of a footing resting on a slope crest, but foundations in most infrastructure projects are usually built at some depth below the ground surface. Therefore, the availability of some form of design charts for determining the factor of safety of a slope supporting an embedded footing will be highly useful for the practising engineers. In the current work, the finite element analysis of a sandy soil slope supporting an embedded footing was carried out using the Plaxis 2D, a finite element-based commercial software, in order to examine the effect of slope geometry, soil properties, and footing locations on the stability of slope in terms of factor of safety. The results of the analysis show that the factor of safety of the slope increases with an increase in the footing edge distance, footing depth and soil relative density, but it decreases with an increase in the slope angle and applied pressure on the footing. Some design charts have been developed along with an illustrative example to explain how these charts can be used by the practising engineers.

“…Due to higher tensile strength and longer length, there is a downfall in the displacement of the earthen embankments and increase in the safety factor. When the loading is applied at the top of the earthen embankment, the displacement increases which decreases the safety factor [44]. Improper draining in construction may lead to the failure of geogrid reinforced slope.…”

“…Geogrids in slopes may be uneconomical as lengthy geogrids increases the cost of construction [43]. However, it can be said that geogrids used in slopes as reinforcement increases the slopes' stability [40] - [44].…”

“…Geogrids, commonly known as geosynthetics and polymer grids, are commonly used for stabilization (pavements), protection (slope stability), drainage and strengthening [2]. For instance, geogrids are used for reinforcing retaining walls [3]- [9], pavements [10][11][12][13][14][15][16][17][18], foundations in soft soil [19]- [39], slope stability [40]- [44], embankments [45]- [47] and for structural components such as beams and columns [48]- [68]. The usage of geogrids may be considered as highly economical and safe towards the environment as it creates less environmental effects [69].…”

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
