Overview

Numerical modeling reveals reduced foundation settlement with wraparound geotextile reinforcement under tailings dam embankments, indicating enhanced structural stability against deformation.

Key Points

  • To evaluate the load-settlement response of a gold tailings dam foundation reinforced with single-layer woven geotextiles featuring wraparound ends under embankment loading.
  • Simulated foundation settlement under dam embankment loads using commercial finite element (FE) software.
  • Modeled single-layer biaxial woven geotextiles with and without wraparound ends across varying burial depths and shear strength parameters (internal friction angle and cohesion).
  • Foundation models utilizing wraparound reinforcement ends achieved greater settlement reduction compared to models without wrapped ends.
  • Increasing the foundation angle of internal friction from 30° to 35° under constant cohesion improved the settlement ratio by up to 11% in wraparound models.
