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.

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.
Tunnelling and geotechnics — new horizons Antonio Gens: State-of-the-art report and theme lecture. Geotechnical engineering and frontier resource development David Henkel: Time-dependent ground movements and tunnel lining distortions occurring after tunnelling are discussed, their magnitude depending on the relative permeability of the tunnel lining and soil, the degree of anisotropy of the soil permeability, and the initial pore pressure prior to tunnelling.

The settlements above the tunnel continued to develop for up to days after the primary lining installation.
Triaxial compression tests were carried out to estimate the short-term and long-term deformation characteristics of the till. Dr Qianbing Zhang is a Lecturer of the Department of Civil Engineering at Monash University.
He is undertaking research on geotechnical and underground engineering. Dr Zhang completed his PhD in at Swiss Federal Institute of Technology in Lausanne. This new road construction project is located on the west coast of Hong Kong Island and traverses the side of a high, unstable natural slope/cliff-line that had significant geological, geomorphological and topographical calgaryrefugeehealth.com: Senior Consultant / Divisional .Download
