Analysis of Pull-Out Behavior Characteristics of Plate Anchor Pin for River Reinforcement Nets Through Field Testing

In this study, field tests were conducted to analyze the pull-out behavior of plate anchor pins used in stone nets, which are commonly applied for river reinforcement. The maximum pull-out load and ground behavior were evaluated based on the length of the anchor pins and the size of the plate. A comparative analysis was also performed with existing theoretical formulas. The field test results showed that the maximum pull-out load was directly proportional to the length of the anchor pins and the surface area of the plates. Furthermore, the comparison with theoretical formulas indicated that the ultimate pull-out load observed in the field tests exhibited similar trends to the M&A and D&C theoretical models, depending on the installation depth and plate width. It is expected that continuous research and field tests under various ground conditions will contribute to improving the design and performance of river disaster prevention structures.
