Abstract

A reinforcement open caisson of a bridge was constructed on a sand island. Its constructing characteristic couldn't been foreseen and were calculated conventionally. Besides, there were some mistaken methods in the constructing. Therefore the open caisson broke up to become 4 blocks in the construction. The largest width in these cracks was 80 cm. Investigation and analysis having been done, the causes of the failure were found. Some repairing methods, such as opposite cutting edge, reinforcement hoop, and so on, adopted. Correct excavation was carried out. The open caisson finally sunk to the rock. The treatment was successful.
