Abstract

The technique of reinforcing soil for foundation improvement is well established. In this paper, parametric study using finite element analysis PLAXIS, 8.2 has been introduced to discuss the effect of elastic modulus of clay on settlement in clay beneath center and corner of strip footing at thickness 0.3 and 1.5 m without geogrid layer. Secondly case study the effect of elastic modulus of sand, elastic modulus of clay, and thickness of strip footing on relative settlement Ss-c/Sc (settlement in sand overlay clay over settlement in clayey soil) beneath center and corner of strip footing without geogrid. Third case study the effect of one layer geogrid depth and thickness of strip footing on relative settlement beneath center and corner of strip footing. The results indicated that increasing elastic modulus of clay decreases settlement beneath center and corner of strip footing without geogrid. The settlement in case of sand overlay clay beneath center and corner of strip footing without geogrid decreases with increasing elastic modulus of sand over clay. In case of using geogrid, sand layer was used overlay the clay bed. In addition, the relative settlement beneath center and corner of strip footing with geogrid increases with increasing depth of geogrid. It has been observed that the difference in settlement between points A and B in thickness 0.3m greater than 1.5m because of strip footing rigidity with soil.
