“…loose and medium dense sand) materials can substantially be improved by introducing the reinforcing elements, like geogrids, geotextiles etc., within the significant zone of influence with a suitable layout arrangement and configuration. The beneficial effects of using tensile reinforcement to increase the bearing capacity of soil have been clearly demonstrated by several investigators (Binquet and Lee 1975a, b;Akinmusuru and Akinbolade 1981;Das and Larbi-Cherif 1983;Fragaszy and Lawton 1984;Guido et al 1986;Huang and Tatsuoka 1990;Dixit and Mandal 1993;Khing et al 1993;Murthy et al 1993;Omar et al 1993a, b;Yetimoglu et al 1994;Adams and Collin 1997;Yoo 2001;Kumar and Saran 2001;2003a, b, c;2004;Kumar et al 2005). For designing foundations subjected to earthquake forces, adopting appropriate values of horizontal and vertical seismic coefficients, equivalent seismic forces can be conveniently evaluated.…”

In the present paper, a method of analysis for calculating the pressure intensity corresponding to a given settlement for eccentrically and obliquely loaded square and rectangular footings resting on reinforced soil foundation has been presented. The process has been simplified by presenting non-dimensional charts for the various terms used in the analysis, which can be directly used by practicing engineers. An approximate method has been suggested to find out the ultimate bearing capacity of such footings on reinforced soil. The results have been validated with the model test results. The procedure has been made clear by giving an illustrative example.

“…One new application, the construction of reinforced soil foundation to support a shallow spread footing has a considerable potential as a cost-effective alternative to conventional methods of support. The beneficial effects of using tensile reinforcement to increase the bearing capacity of sands have been clearly demonstrated by several investigators (Binquet and Lee, 1975a, b;Akinmusuru and Akinbolade, 1981;Das and Larbi-Cherif, 1983;Fragaszy and Lawton, 1984;Guido et al, 1986;Huang and Tatsuoka, 1990;Dixit and Mandal, 1993;Khing et al, 1993Khing et al, , 1994Murthy et al, 1993;Yetimoglu et al, 1994;Adams and Collin, 1997;Saran, 2001, 2003a, b). In general, settlement is the governing criterion for designing a footing resting on weak granular material.…”

Pressure–settlement characteristics of rectangular footings on reinforced sand

A method has been proposed to obtain the pressure-settlement characteristics of rectangular footings resting on reinforced sand based on constitutive laws of soils. The confining effect of the reinforcement provided in the soil at different layers has been incorporated in the analysis by considering the equivalent stresses generated due to friction at the soilreinforcement interface. The prerequisite of the method is the value of ultimate bearing capacity, which can be obtained from the approaches already available in literature. The value of settlement may be read directly from pressure-settlement curves for the given pressure intensity. Therefore, the rectangular footing resting on reinforced sand can be proportioned satisfying shear failure and settlement criteria.

“…Since the original work by Binquet and Lee, several laboratory model test studies have been published relating to the improvement of the load-bearing capacity of shallow foundations supported by sand reinforced with various materials such as geogrids [3,4], geotextiles [5], rope fibers [6], metal strips and metal bars [7][8][9][10][11][12].…”

Numerical analysis of shallow foundations on geogrid reinforced soil

2017

View full text Add to dashboard Cite

Abstract.Geogrids have been increasingly used as soil improvement technique over the past decade. This increasing trend is attributed to its ease of application and low cost compared to other improvement techniques. This paper provides a review of the published results related to the ultimate and allowable bearing capacities of shallow foundations on geo-grid-reinforced homogeneous sand soil. A numerical analysis is also conducted to investigate soil-geogrid interaction considering several critical parameters that affect the overall behavior of geogrid-reinforced soil. The critical parameters such as the width and length of geogrid layers, spacing between the reinforcement layers, and the depth of reinforcement and geosynthetic stiffness have been investigated.
