STANDBY FOR HIGH RISK TASMAN

The design report on a second hobart bridge, for which the Australian federal government has just committed found16M, has stated that there is one chance in three of another collapse of the tasman bridge at hobart, tasmania, within the next 10 years, caused by a ship again colliding with one of the piers. Details are given of the reconstruction of the bridge which collapsed. The need for a second hobart bridge and its design aspects are indicated. It is estimated that the bridge should take about three years to build. Massive gravity caissons extending down to bedrock as much as 45 M below water level are recommended. Each caisson is designed to resist impact at any angle from a 5000 t ship travelling at 12.6 km/h. The outer shell will consist of driven h-section steel piles filled with concrete and the inner shell will be 500 mm thick reinforced concrete. (TRRL)
