Abstract

Abstract

In this work we investigated the damage effects on the caisson gravity wharf using an on-situ test of the wharf model under 1 kg TNT explosion in air, in water and inside the internal structure, and obtained the corresponding damage modes of the wharf model under the different explosion conditions, with the emergent repair proposals presented addressing to the respective damage modes. The results showed that a blast hole was observed locally on parts on the wharf model's panel for air explosion, that lots of cracks developed on the blast side and nearby area of the wharf model for water explosion, and that under the blast in the wharf model's internal structure, the cabins underwent huge deformations and were destroyed while the middle of the model's panel plate was lifted and thrown away. At the same weight of the explosive charge, the damage degree appears minimum under air explosion while it appears the maximum under explosion inside the model's internal structure.
