스미어 현상이 발생한 암반에 근입된 현장타설말뚝의 주면저항력 산정법 = A Method for Estimating the Shaft Resistance of Drilled Piers Socketed in Smeared Rock

다국어 초록 (Multilingual Abstract)

Just as infill can reduce the shear strength of a rock joint, a layer of soft material between concrete and the surrounding socket can reduce pile shaft resistance. This can result from construction methods that leave smeared or remoulded rock or drilling fluid residue on the sides of the rock socket after concrete placement. Characteristics of the concrete-rock interface, such as roughness and the presence of the soft materials deposited during construction can significantly affect the shaft resistance response of the pile. This study conducts the parametric study to examines the behavioral characteristics of drilled shaft socketed in smeared rock. It is hoped that this will lead to greater efficiency and reliablity in pile design.
