A Viscoplastic Interpretation of Strain Rate Growth in Variably Saturated Soil Systems Subjected to Wetting

Description:

Fluid injection is one of the major triggering factors of infrastructure collapse and geo-hazards, among which some of the most recurrent ones are rainfall-induced landslides. Such events exhibit complicated spatiotemporal patterns, spanning from slow deformation to extremely rapid movements influencing large regions. To prevent the occurrence of catastrophic failures and...

An Incrementally Non-linear Model for Clays with Directional Stiffness and a Small Strain Emphasis

Description:

In response to construction activities and loads from permanent structures, soil generally is subjected to a variety of loading modes varying both in time and location. It also has been increasingly appreciated that the strains around well-designed foundations, excavations and tunnels are mostly small, with soil responses at this strain...
