THE CASE FOR STEEL PLATE TUNNEL LININGS

The case for steel tunnel linings is presented. The author suggests the development of a steel lining for tunnels consisting of plates machine-cut to size, transported flat to the construction site, and then rolled to the required radius. The ground deformations would be accommodated by the elastic and ductile straining of the ring as a whole, locating lugs would be provided to assist erection, and joints would be made watertight by sealing welds. The cost of fabrication and site welding is estimated to be around $35 per ton. The importance of perfect circularity and uniform hydrostatic pressure is discussed. /TRRL/
