“…The role of reinforcement in improving the bearing capacity of foundation soils has been investigated by several researchers, such as Fragaszy and Lawton (1984), Huang and Tatsuoka (1990), Khing et al (1993), Yetimoglu et al (1994), Shin and Das (2000), Dash et al (2003), Michalowski (2004), Patra et al (2005Patra et al ( , 2006, Basudhar et al (2006), El Sawwaf (2007), Moghaddas Tafreshi and Dawson (2010), Yadu and Tripathi (2013) [1][2][3][4][5][6][7][8][9][10][11][12][13]. The focus of most of these studies was on strip footing models and the length of reinforcing layers for achieving maximum bearing capacity found to be in a range of 5 to 8 times of footing width.…”

This paper aims to investigate the likely e ects of geogrid reinforcement con guration on the bearing capacity of footings. Using geogrid reinforcement layers with certain total areas in various uniform and non-uniform arrangements, the bearing capacities of footing models on reinforced sand beds were determined and compared. The rst arrangement was the conventional uniform layout in which three geogrid layers of equal dimensions were considered. In the second group, the same amount of geogrids was used in a trapezoidal pro le in which smaller sized geogrids were placed at upper layers and the geogrid dimensions increased with embedment depth. The third group consisted of arrangements in which the same amount of geogrids was used in an inverse trapezoidal layout, i.e. the layer sizes decreased with embedment depth. The e ect of soil density on the footing performance was also investigated. The tests results indicated that in all soil densities, the greatest bearing capacities were obtained for the sand beds reinforced with inverse trapezoidal reinforcement layouts, while the least bearing capacities were determined for trapezoidal arrangements. The improvement ratio of bearing capacity due to geogrid reinforcement varied from 1.8 to 5.35 depending on the reinforcement layout and the sand bed density.

“…The value of the Bearing capacity Ratio (BCR) is the value obtained from the comparison between the bearing capacity of the reinforced soil (qu) and without reinforcement (qo) which in this study is used as a benchmark to measure how much effect of the variables used in the reinforcement [12]. The results of the tests applied the reinforcement of cajelput cerucuk material can increase the value of BCR.…”

Most of the land in South Sumatera is the problematic soil, one of that is peat. Peat has low soil bearing capacity, and it becomes a problem when construction is built. Before the installation process, it is necessary to handle that soil. Soil improvement that can be done on peat to increase the bearing capacity value is the reinforcement method or physical stabilization. The results of research on woven bamboo and cerucuk are used as reinforcement material, which is expected to be an alternative to improve soil bearing capacity. The research methodology used was on the scale of the laboratory and analyzed by comparing the soil bearing capacity without reinforcement in bearing capacity ratio (BCR). The maximum bearing capacity with cerucuk reinforcement and without woven bamboo is 39.33 kPa with variations of the two outer rods of the left and right sides from 750 angle toward the foundation plane. However, using the 3 layers of reinforcement woven bamboo that is combined with cerucuk, which has diameter 1,5 cm and length 60 cm generates the highest soil bearing capacity value. The maximum of bearing capacity is 58 kPa. The BCR is 10,88 or in percentage is 988,2%, or 10 times greater than bearing capacity without reinforcement. So, it can be inferred that woven bamboo and cerucuk are used as an alternative to improve bearing capacity on peat soil.

“…The bearing capacity depends on the length of the geogrid layers. For footings, the geogrid reinforcement increases the bearing capacity and limits the settlement [39].…”

“…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
