...J. Sang-Iam; J.A. Smethurst; W. Powrie Unlike modern earthworks, historic railway embankments were often end-tipped rather than compacted in layers and are susceptible to significant deformation and potentially failure. This study assesses the mechanical and hydraulic behaviour (deformation, stress...

The shear strength and deformation of PG were significantly affected by dissolution and recrystallisation. Dissolution weakened the cementation between...
