Abstract
Problem statement: During the past few years a great number of experi mental model and numerical analysis results on the uplift resistance of anchor plate embedded in homogeneous cohesion less soil has been reported by many researchers. A review of related literature shows that not much research has been done to analyze the performance o f anchor plates in layered soils a problem, which is often encountered by the professional engineers in the field. Approach: This study presented the performance of the anchor plates in the cohesion le ss soil by different researchers. It was based on different previous researches, from the earliest ti ll the most recent ones. The main aim of this resea rch was focused on the prediction of the anchor plate's behavior and the force in the layered cohesion les s soils. Few laboratory studies were conducted to inv estigate the uplift capacity behavior of cohesion less soil by previous researchers. Results: The experimental and numerical investigation inclu ded uplift test on cohesion less soil by last researche rs. The embedment ratio and the effect of density o n uplift response were evaluated. This analysis was i nvestigated experimentally and numerically behavior of anchor plates buried in two layered coh esion less soil. Although earlier researchers developed experimentally expressions to estimate th e uplift capacity of irregular anchor plates in layered cohesion less soils. Conclusion: The study observed that the ultimate uplift capaci ty is dependent on the relative strength of the two layer s, the depth ratio of embedment and the upper layer thickness ratio.
Highlights
Based on a large number of laboratory model and large-scale test results many investigators reported the pullout resistance of anchor plates embedded in homogeneous soils, A review of related literature shows that not much work has been done to determine the ultimate pullout capacity in a two-layered soil, a problem that is often encountered in field
Experiment, beginning from Bouazza and Finlay (1990) that they reported the behavior of an anchor plate buried in a two layered cohesion less soil
This study shows that the last experimental tests and numerical analysis have been done regarding to performance of the anchor plate in layered cohesion less soil
Summary
Based on a large number of laboratory model and large-scale test results many investigators reported the pullout resistance of anchor plates embedded in homogeneous soils, A review of related literature shows that not much work has been done to determine the ultimate pullout capacity in a two-layered soil, a problem that is often encountered in field. It was reported that for upper layer thickness ratio of less than one and for a given embedment ratio, D/B there was no difference between the pulling an anchor plate from a dense-medium bed or a dense-loose bed. For the present analysis he had chosen published properties of Chattahoochee River cohesion less soil both at dense and loose conditions (Vesic and Clough, 1968).
