PIV analysis of ground during horizontal pile loading by centrifuge tests
PIV analysis of ground during horizontal pile loading by centrifuge tests
Examining the ground’s deformation characteristics is valuable in assessing the impact of ground behavior around piles on horizontal resistance. In this study, horizontal pile loading experiments in a centrifugal 50G field and PIV image analysis were conducted. The ground deformed three-dimensionally when the pile was loaded horizontally. Therefore, two experiments were conducted: one to observe the ground surface and another to observe the ground section. The displacement distribution of the ground surface was nearly circular, while that of the ground section was triangular in the initial stage of loading and became quadrangular as the pile head displacement increased. The size of the three-dimensional deformation area of ground in front of a pile at each loading stage was analyzed, and the results indicated that the horizontal resistance of a pile is related to the size of the deformation area of the ground.
