DESCRIPTION:This presentation will discuss how a number of monitoring inst
 ruments were installed within two sections of an existing grey cast iron s
 egmental tunnel lining (the Post Office Tunnel) before the works of Crossr
 ail and London Underground pass beneath\, in a parallel and perpendicular 
 configuration respectively. The monitoring instruments were made up of dis
 placement transducers\, vibrating wire strain gauges and distributed optic
 al fibre strain sensing. Results from these sensors have started to shed n
 ew light on the response of these existing cast iron structures to ground 
 movement. \n\nNow using this observed data to calibrate the boundary condi
 tions in a detailed structural FE model\, the method of developing the mod
 el\, with empirically calculated imposed ground movement will be presented
 \, and from this\, the mechanisms of the tunnel lining displacements under
  these conditions can be interrogated\; with the overall goal of better un
 derstanding the structural performance\, and improving the methods by whic
 h these assets are routinely assessed.
