Abstract

A wide variety of instrumentation was deployed during the construction of the sprayed-concrete lined tunnels at Heathrow Express Terminal 4 station. This paper presents data from the in-tunnel displacement monitoring system and for settlements above the tunnels, providing data on instrument survival and performance, and an overall summary of the displacements arising from tunnel excavation.
