Overview

Tests reveal pull-out behavior and reinforcement mechanisms of polyester yarn geogrids, indicating optimal installation techniques.

Key Points

  • The study aims to investigate the mechanical characteristics and reinforcement mechanisms of polyester yarn bundle geogrids in retaining structures.
  • Conducted pull-out tests at different rates and water contents
  • Developed a DEM-FDM coupled numerical model for analyzing pull-out behavior
  • Analyzed load-bearing characteristics through theoretical methods
  • Identified a critical pull-out rate of 1 mm/min maximizing pull-out resistance
  • Observed interface friction angle decreases with pull-out rate, while cohesion increases
  • Noted significant weakening effect on soil-geogrid interface strength with low stress conditions
  • Discovered that sliding frictional resistance constitutes 80% of total resistance during pull-out process
  • Classified shear failures based on normal stress levels
