Static  Analysis
Geological studies and investigations  have led to the definition of the geomechanical  characteristics of the soils to be used in the numerical analysis. In the following, a summary of  these characteristics is reported in Table E. The mechanical properties of the structural  elements are shown in the previous Figure 5. 
The static analysis carried out by the  application of all the before mentioned vertical loads has pointed out the  characteristic behaviour of the retaining  walls of the Metro Station’s structure: it appears similar to a double  multi-span (simply supported) beams. 
The  structural conditions of the Metro Station under the considered static loads  are determined by performing a construction stage analysis, taking into account  all the main phases historically involved in the construction of the station.
