Kinematic behaviors of piggy-backed vertically loaded anchors in clay

This paper investigated the kinematic behaviors of piggy-backed anchors composed of two vertically loaded anchors. The embedding tests were conducted using two Dennla anchor models with a 1:30 scale by 3D printing technology. The orientation and motion of the model anchor were continuously monitored during the embedment process by a 6-DOF magnetometer system. This study, which included six groups of tests, provided a comprehensive investigation of the trajectory, installation load, pitch angle and fluke-shank angle of vertically loaded anchor (VLA) embedding, considering factors such as spacing, attachment point, initial fluke-shank angle and aspect ratio load. The findings of this research will enhance the comprehension of VLA performance in tandem systems and optimize the design and combinations of piggy-backed VLAs.
