판앵커의 인발 속도에 따른 극한 인발저항력 분석

Abstract

Anchors are primarily designed and constructed to resist outwardly-directed loads imposed on the foundation of the structure. These outwardly-directed loads are transmitted to the soil at a greater depth by the anchors. Buried anchors have been used for thousands of years to stabilize the structures. Various types of earth anchors are nowadays used for the uplift resistance of transmission towers, utility poles, submerged pipelines and tunnels. Anchors are also used for tieback resistance of earth-retaining structures, waterfront structures, at bends in pressure pipelines, and when it is necessary to control thermal stress. In this research we have analyzed the uplift behavior of plate anchors in sand and clay by laboratory experiment to estimate the uplift behavior of plate anchor in various conditions. To archive the research purpose, uplift resistance and displacement characteristics of plate anchors caused by embedment ratio, plate diameter, loading rate were studied, compared and analyzed with various cases.
