Soil is considered to be the cheapest material in the construction of embankments, earthen dams, and retaining walls. Hence it becomes necessary to improve the stability of such structures. Various techniques have been adopted to increase the stability. Some of them are soil stabilization, soil reinforcement, grouting, soil nailing etc. Each of these techniques has its own limitations. Geo-anchors, a new method is adopted to increase the stability of steep slopes, to reduce the lateral earth pressures on retaining or sheet pile walls or to stabilise embankments constructed on soft clay. In this method geo-anchors are used which are constructed by lining narrow trenches with high-strength geotextile and by filling the trenches with coarse sand, gravel or crushed rock. The granular material should be compacted in thin layers to increase the effectiveness of the method. A method to calculate the stabilising effect of the geo-anchors for different applications is described. In the present work, numerical analyses have been carried out using PLAXIS to study the performance of geo anchors in embankments and sheet pile walls. The study was carried out by varying the number of geo anchors and the position of the geo-anchors. It is observed that the performance of the geo structures improved by providing geo-anchors. Further the performance of geo-anchors largely dependent on the spacing and the number of geo-anchors. So it is mandatory to carry out the analysis to select the proper spacing and number of geo-anchors for any such earth retaining structures.
