Recent developments in the design of cut and cover construction for railway tunnels and stations

As we move into the next millenium the demand for mass transit railways to be built in urban locations is increasing and this inevitably means that long lengths of track have to be constructed below ground. The design of cut and cover tunnels needs to consider many factors including resistance to flotation, soil lateral loads, water pressure, overburden, superimposed loads, construction loads, de-waterinq, effects on adjacent structures, settlement, sequence of construction, water tightness, drainage, ventilation, piston effects, rolling stock clearances, fire and passenger evacuation etc. Constructability, maximising overhead development potential and minimiSing project cost, environmental effects, and traffic congestion due to construction are also critical factors. This paper describes these issues and how they may be addressed. This paper also describes the design of cut and cover stations at North Greenwich and Canada Water as part of the Jubilee Line Extension on the London Underground and the design of cut and cover tunnels on the New Airport Line in Hong Kong.
