Abstract | The recent flood events in Queensland, Australia had an adverse effect on the country's social and economic growth. It is reported in the recent literature that due to climate change, frequency of flood events has increased as well as they have become more intense. This research paper focuses on the damage caused by the recent floods in Queensland, on the bridge infrastructure. Bridges affected by 2013 flood in Lockyer Valley region in Western Queensland were selected as a case study. For the damaged bridges, data such as level of damage, material used in these bridges, type of bridge (girder/precast/in-situ), age of the bridge, elevation of the bridge from the mean sea level, annual average daily traffic, class of the bridge, heavy vehicles and inspection data before and after the flood were collected and analysed. This case study aims at identifying all the attributes of bridges contributing to failure such as bridge approaches, bridge surface, waterway, bridge substructure, bridge superstructure etc. It further analyses the failure mechanisms of different types of bridges (Concrete, In situ, pre cast etc.) and identifies the relationship of the component failure of a bridge to the overall failure of the infrastructure system. Major failure mechanisms were identified as deck and the bridge approach, pier/abutment scouring, significant built up of mud and debris on the structure and approaches, cracks in the abutment wing walls and misalignment of abutment headstock connection to piles. It is interesting to observe that there is an inverse relationship between the age of the bridge and the damage level. The reasons for this could be due to different construction practices adopted in the past or they had been rehabilitated after previous disaster event. In order to analyse and confirm these reasons, possible bridge design codes used for the bridge in question have been identified. |
