• Abstract:
  The stability of MSE walls may be compromised in undrained conditions such as during a heavy rain or during a rapid drawdown. Excess pore pressures in low permeability soils may not dissipate quickly enough and thus may reduce the effective stresses inside the soil, which in turn may cause a reduction of the shear strength at the interface between the soil and the reinforcement. The study of MSE walls in undrained conditions is needed to determine the behavior of saturated MSE walls where rapid changes in pore pressures are anticipated. For this purpose, a series of laboratory pullout tests are performed under drained and undrained conditions for different soil types ranging from clean sand to 35 % silty sand and for overburden pressures of 30, 100 and 200 kPa. Numerical analyses are also conducted to determine scale and permeability effects for the dissipation of excess pore pressures.
