  Experimental Study on the Effect of Localized Weak Zones on the Seismic Behavior of Shallow Tunnels

  Abstract: Weak zones around the tunnel lining may be formed because of the poor workmanship, inadequate back-filling, weathering or erosion. The situation is more complicated as such weak zones formation behind the lining, may not be readily spotted until substantial damage to the lining has been produced. Several case histories showed that the main factors for the failure of tunnels were the weak zones...
