MSE Wall – Mechanically Stabilized Earth Walls design

 

The program is used to verify mechanically stabilized earth walls and segmental retaining walls reinforced by geogrids.

 

Main Features

  • Built-in database of available georeinforcement (geogrids) – Fortrac, Tensar, Miragrid, KB-grid, Acegrid, Secugrid, Enkagrid
  • Simple and clear input of reinforcements, automatic generation of reinforcement position
  • Various kinds of slopes: prefabricated blocks at the front face of the wall, simple slope or slope with berms (including optional cover)
  • Verification of internal stability - direct sliding of soil block on georeinforcement, tearing and pull-out strengths of georeinforcement
  • Verification of global stability at circular slip surface (Bishop, Spencer)
  • Verification analysis can be performed employing EN 1997-1, LRFD or classical approach (limit states, factor of safety)
  • EN 1997 - option to choose partial factors based on National Annexes
  • EN 1997 - option to choose all design approaches, consider design situations
  • Generally layered soil environment
  • Built-in database of soil parameters
  • Arbitrary number of analyses in one example
  • Multiple construction stages
  • Arbitrary number of surcharges applied to structures (strip, trapezoidal, concentrated load)
  • Arbitrary number of inserted forces (anchors, safety fences, etc.)
  • Modelling of water in front of and behind structures, modelling of artesian water
  • General shape of terrain behind the structure
  • Berms in front of the structure
  • Various types of pressures in front of the structure (at rest, passive, reduced passive)
  • Possibility to not consider pressure in the front
  • Calculation of earth pressures in effective and total parameters
  • Earthquake effects (Mononobe-Okabe, Arrango)
  • Verification of fictitious wall against translation and overturning
  • Verification of bearing capacity of foundation soil
  • Verification of translation and overturning of arbitrary part of the wall (dimensioning)
