<p>This paper deals with full face excavation of large size tunnels in rock masses of very poor quality which exhibit squeezing behaviour. Time dependence is accounted for explicitly by using constitutive models which have been validated with reference to ...

The purpose of this paper is to present test data withing a theoretical framework which allows some relationships to be established between the different time dependent phenomena. It is demonstrated that certain relationships between the different types of ...

Virtually every soil "lives" in that all of its properties undergo changes with time - some insignificant, but others very important. Time-dependent chemical, geomicrobiological, and mechanical processes may result in compositional and structural changes that ...
