• Abstract:
  Bridge approach embankments and many other
  
  transportation-related applications make use of
  
  reinforced earth retaining structures. Mechanically
  
  Stabilized Earth (MSE) walls are designed under
  
  the Load and Resistance Factor Design (LRFD)
  
  methodology, and make use of calibrated load
  
  and resistance factors to check for internal
  
  and external stability. This study focused on
  
  the calibration of resistance factors for bearing
  
  resistance with horizontal ground and sloping
  
  ground in front of MSE walls using scaled models.
  
  In this project, University of Florida researchers
  
  developed resistance factors for MSE walls
  
  subject to sliding and bearing by considering the
  
  influences of variability in soil parameters as
  
  well as different analysis methods (coefficients
  
  of variation, or CVs) using numerical and physical
  
  modeling. Furthermore, load factors for vertical
  
  and horizontal earth pressures were determined
  
  and compared to other reported values as well as
  
  current practice.
