Session 01: Case Histories of Unexpected Behavior and Failure of Shallow, Deep and Other Foundations

Abstract
The construction of the bridge near Pöchlarn over Danube, in Austria was begun 1998 and completed in 2002. The four middle piers of the bridge consist of sink caissons made of pre-cast reinforced concrete elements. Each caisson is founded on 18 bored piles of 1.2 m diameter. In a first step, two pilot piles of about 40 m length are installed for each caisson. After the pilot piles were completed, an accident happened in April 1999. A cargo ship collided with the pier no 3 and damaged the two pilot piles. Since the piles were below water level, it was very difficult to inspect the damage. Therefore, integrity tests were carried out to know the level of damage. The possible scenarios range from local repair to installation of new pilot piles. The paper describes a case study of the repair works of the damaged piles, where under water pile integrity tests were carried out.
