Abstract:

The pull-out resistance of reinforcing parts is one among the most vital factors in increasing bearing capability. During this analysis a new reinforcing element that features attaching components to normal soil for increasing the resistance strength of reinforcements is introduced. The objective of the present work is to analyze performance of geogrid reinforcement placed below the footing on non-homogeneous soil and to investigate the behavior of geogrid- reinforced beds by analytical study. The work presented in the thesis will lead to a better understanding of the mechanism of foundation on geogrid reinforced soil beds. Based on results obtained from the current investigation it is said to be that the saving is created in subsoil depth for constant collapse settlement performance by victimization geogrid reinforced foundation system. A load settlement response was measured when geogrid reinforcement was provided. The stiffer response was determined at a comparatively a lot of reduction in settlement concerning 28.77% and 27% for foundation model to u equals to 0 and 150mm respectively. A load and stress response was measured when a geogrid reinforcement was provided and a response was determined that, comparatively a lot of reduction in stresses concerning 50.24% and 49.15% for foundation model comparable to u equals to 0 and 150mm respectively. It is determined that comparatively a lot of reduction in total elastic strain concerning 47.71% and 19.37% comparable to u equals to 0 and 150mm respectively. The results were obtained from the analysis indicates that a depth of placement of geogrid reinforcing layer is below the footing that is u=0mm and u=150mm for layered foundation conditions.
