Visual Nastran dlya Windows. For the post-construction consolidation period ' was assumed to be equal to zero. All the other strata were modelled as isotropic non-linear elastic perfectly plastic materials.

For the lower horizontal boundary neither vertical nor horizontal movements were allowed. It was observed that the magnitude of the settlements was driven by the overall effects of the tunnels, which were assumed to act as perfect drains, on the initial pore water pressure regime.

Geotechnics

A Critical State Approach, Second Edition continues to cater to a wide range of readers, from graduate students through to engineering practice. One of the reasons for these post-construction, or long-term, movements is that tunnels act as drains and reduce pore water pressures in the surrounding clay, thereby increasing the effective stress and causing consolidation to occur.
