NEW IDEAS ON TUNNEL STATICS

NUOVI CONCETTI SULLA STATICA DELLE GALLERIE

The article examines the problem of tunnel statics in its most general form, specifying the basic characteristics, the simplifying hypotheses and basic elements to be used for a correct solution. After a brief review of the classical solutions available, the problem is analysed by considering the characteristic lines, the conditions of the attack surface, the influence of the weather and cases of stability. The article consequently defines the main characteristics of the problem of tunnels, and concludes that the two basic issues, as regards tunnel statics, are the three-dimensional states of stress at surface level and the viscous behavior of the rock, which influence one another. Finally, the new rheological principles are explained, on the basis of the definition of the corresponding laws and the resulting models.
