Abstract: |
The new Bologna high-speed railway station extends approximately 640 m underground, with a width of 56 m and a depth of 25 m. The open-cut excavation work to complete the underground station was designed using an innovative structural system, which entails the construction of reinforced concrete diaphragm walls with unusual shape and structural behaviour. Vaults, diaphragm walls with an arched section, were constructed to absorb the thrust actions. Buttresses, T-section diaphragm walls were designed to absorb actions through flexural behaviour transmitted by the vaults. |
