STRESSES IN LININGS OF BORED TUNNELS

An analytical procedure is presented for evaluating the stresses in li nings of bored tunnels caused by kinematic soil-lining interaction. Th ree cases of plane-strain interaction are treated as produced by (1) r elaxation of in situ soil stresses near a lining following its install ation, (2) overburden pressure at the soil surface, and (3) two-dimens ional free-held soil response normal to the lining axis as produced by an earthquake. The procedure is applied separately to a steel lining and a concrete lining for a site located at the lower end of Market St reet in San Francisco through which a BART (Bay Area Rapid Transit) tu nnel passes.
