Abstract: Retaining walls that do not move are customarily designed based on the assumption of at-rest conditions, with no consideration of vertical shear loads applied by the backfill. However, field and laboratory measurements ...

Abstract: Design of column-supported embankments (CSE) requires the evaluation of global stability using the conventional limit equilibrium method (LEM). Yet, for CSEs using unreinforced concrete columns and load transferring geogrids, ...

Abstract: Progressive failure can occur along geosynthetic interfaces in lined waste landfills when peak strengths are greater than residual strengths. A displacement-softening formulation for geosynthetic interfaces was used in ...

Abstract: New displacement-softening and work-softening models were developed to describe the sliding of geosynthetic interfaces, such as those in landfill liners. The displacement-softening formulation is based on the assumption ...

Abstract: Statistical analyses of data sets from five case histories indicate that soil–bentonite hydraulic conductivity is distributed log normally. The advection–diffusion equation was used to investigate the impact of log-normal ...

Abstract: Massive concrete walls constructed on rock foundations, as well as other nonmoving retaining walls, are customarily designed for at-rest earth pressures. Vertical shear loads applied by the backfill are usually not considered ...

Abstract: Three important mechanisms that contribute to the compression of municipal solid waste are instantaneous compression in response to applied load, secondary mechanical creep, and time-dependent biological decomposition. A ...
