AVON RAIL TUNNEL, NEW SOUTH WALES
The avon tunnel on the maldon -port kembla railway will be the longest rail tunnel in Australia and will comprise a single track of horseshoe section with a 6.0 m nominal diameter and a length of 4024 m at a grade of 1:30. The route chosen was the most environmentally acceptable and safest route from the point of view of geology and mine workings. Survey data was collected at time intervals to detect any mass ground movements using the global positioning system. The geology of the area is described and the possibility of subsidence due to coal mining, both past and predicted, discussed. To assist in tunnel design an engineering classification of rock masses known as 'rock mass rating' was incorporated into the investigations. Rock conditions at one section of the geology can be correlated with those at other sections or from previous sites and the behaviour and support requirements of the rock mass predicted. Tunnel excavation will be by drill and blast methods and brief details are given of the quantities involved. (TRRL)
