Design methods of tunnels: stability settlements and tunnel lining

摘要

For this section 20 papers were submitted. Most of these papers dealt with models for design purposes; i.e. the development of models, the use of models or the validation of models. With respect to the latter the measurements; based on monitoring or (lab) experiments which were prescribed, always are a valuable source for further developments. To begin with a number of papers is discussed which are related to specific projects: the design, the organisation and the construction of engineering works. The second section is related to construction, i.e. to a construction technique, not being specifically related to one project. The third section, to which the largest number of papers is related, is design and analysis. That is, the use of empirical, analytical, numerical or physical models and optimisation techniques to derive at a design. Finally, some of the papers can't be linked directly to one of the other sections, which makes it worthwhile to discuss these under special issues.
