A high-speed railway viaduct experienced a sustained heave at high rates after its construction. The pillars of the bridge are founded on an Eocene hard anhydritic-gypsiferous claystone by means of massive foundations.

The construction of the bridge is supposed to have triggered the swelling mechanism. An emb...
