      다국어 초록 (Multilingual Abstract)

      Friction anchors are gaining popularity in civil structures. However, the bond length can be increased to use the friction between the ground and friction anchor body. They are often bonded deep in the ground and fixed to the bedrock; this causes problems, including the anchor overlapping the underground structure or invading the lower part of another structure when anchors are installed in downtown sites. Herefore, combination anchors that combine the advantages of plate anchors that resist uplift because of the ground’s bearing capacity with a friction-type anchor have gained attention. However, the ground failure mechanism of plate anchors applied to combination-type anchors has not been accurately analyzed; therefore, various theoretical anchor uplift capacity formulas have been proposed. A model test was performed in this study by forming a sandy ground in a state of plane strain to verify the uplift capacity of the plate anchor installed at a shallow depth and ground failure mechanismPhotos obtained from experiment were evaluated to analyze the shape of the ground failure of the plate anchor. Furthermore, by classifying the depth of the installed anchor, an equation for calculating the ultimate uplift capacity of the plate anchor was proposed according to the classified depth. A model test was performed in this study based on the formation of a sandy ground in a state of plane strain to verify the uplift capacity of the plate anchor installed at a shallow depth and ground failure mechanism. Photos obtained from experimental tests were evaluated to analyze the shape of the ground failure of the plate anchor. Furthermore, by classifying the depth of the installed anchor, an equation for calculating the ultimate uplift capacity of the plate anchor was also proposed according to the classified depth.
