The purpose of this study is to clarify the mechanism of pull-out resistance for shallow suction foundation in clay layer and to propose a method estimating the pull-out resistance. The effects of penetration depth, open ratio, cohesion of clay layer and pull-out velocity on suction and pull-out resistance are investigated through a series of laboratory experiment and a finite element analysis which is introduced to look deep into the failure mode of suction foundation. The theoretical pull-out resistance is compared with the measured one in order to investigate the validity of proposed equations on the pull-out resistance. The following main conclusions are obtained from the study; 1) three different failure modes are experimentally and analytically confirmed to exist, 2) suction and pull-out resistance are affected by the penetration depth, open ratio, cohesion of clay layer and pull-out velocity, 3) the pull-out resistance becomes larger respectively as the cohesion of clay layer, depth ratio of foundation and pull-out velocity increase, and 4) the theoretically estimated pull-out resistance compares fairly well with the experimental one.
