Abstract

Results of parametric study to investigate the applicability of finite element method for analyzing industrial machinery foundation on pre stressed-reinforced embankment over soft soil are investigated in this paper. Model tests were carried out using model footing of 1 m in diameter and geogrids. Particular emphasis is paid on the reinforcement configurations including number of layers, spacing, layer length and depth to ground surface on the behavior of industrial machinery foundation on reinforced silty sand embankment on peat and soft clay under static load is determined. A series of finite element analyses were performed on a slope using two-dimensional plane strain model using the computer code Plaxis. Soil was represented by non-linear hardening soil model, which is an elasto-plastic hyperbolic stress-strain model while reinforcement was represented by elastic elements. Test results indicate that the inclusion of geogrid layers in sand not only significantly improves the footing performance but also leads to great reduction in the depth of reinforced sand layer required to achieve the allowable settlement. However, the efficiency of the sand–geogrid system increases with increasing number of geogrid layers and layer length. Based on the theoretical results. In this paper we can see the effect of pre stressed geotextile is more than that unreinforced and reinforced (without pre stress) embankment.
