This paper describes the detailed engineering design process in terms of the relative geotechnical interpretation stage, the subsequent multistaged numerical simulation steps by using SOFISTIK software, the critical decision making points and the actual results ...

The paper presents a decision making process for the determination of the numerous grouting parameters during design and the necessary corrective and evaluation actions during field trials or systematic grouting. Special application of design and execution ...

<p>This paper describes the design methods and the construction techniques applied at two (2) tunnel sites in Greece, where the highway alignment runs almost parallel to very high and extremely steep mountainous cliffs and slopes in a seaside area. The project ...

This paper describes the design methodology adopted for stabilization measures of a twin bored highway tunnel in Northern Greece, where severe cracking and translational displacements of the temporary support shell were observed. Cracks occurred due to an ...
