The effects of anisotropy and of unhomogeneity of stress state on the lining of road tunnel in a Flysch formation

ABSTRACT

The project provides individual fields of excavation 9 meters long; the inverted segment of the concrete polycentric is build about 20 meters far from the face core, while the polycentric formwork is achieved far about 60 meters.
