Modeling of Uplift Resistance of Buried Pipeline by Geogrid and Grid-Anchor System

This paper presents an experimental and numerical analysis of the uplift resistance pipelines buried in reinforced soil. The behavior system is studied using a set laboratory experiments. pull-out forces some reinforcing are most important factors affecting resistance. Buried elements such as that have high pressure fluids or under temperature need to be order increase their One efficient methods reinforcement increasing involvement between pipe soil by geogrids anchors. grid-anchor recent method for soil, used this study. digital image correlation particle velocimetry (DIC/PIV) measuring displacement field mechanism. We also examined influence parameters An study was performed investigate sand with system. results demonstrate that, pipes diameter 50 mm, can capacity 2.4 times compared conventional geogrid 4 nonreinforced sand. In modeling, likewise, 23 experiments were back-analyzed software FLAC-3D. It became known tests compare well results.
