TYNE AND WEAR METRO, BYKER CONTRACT: PLANNING, TUNNELS, STATIONS AND TRACKWORK

The article describes the design and construction stages for the Byker contract of the Tyne and Wear Metro system. The contract includes a 550 M length of cut and cover tunnel section where the ground consists of coal measures covered by stiff boulder clay with areas of soft laminated clay. As the rocks of the coal measures were found to be standing vertically, an economical form of tunnel was adopted which consisted of thick walls of concrete case against the vertical rock face with a 200 M thick reinforced concrete arch spanning the tracks. The cement for the concrete walls contained 70% blast furnace slag and 30% portland cement. Details are given of tunnel construction methods and track laying techniques.
