MEASUREMENTS OF THE EFFECTS OF TUNNELLING AT YORK WAY, LONDON

The effects of tunnel driving beneath york way, London, on the movement of the ground surface and frontage of a building over the tunnel have been studied by precise levelling and photogrammetry. The ground properties were also determined. Because of the very stable tunnel face and the careful method of tunnel driving, ground surface movements were small, the maximum settlement observed being about 4 mm. The vertical movement of the building frontage was even smaller, the maximum settlement measured being about 2 mm. However, larger horizontal movements of the building frontage were measured, up to a maximum of about 10 mm. Construction of the tunnel also left the building skewed and slightly tilted. The research has demonstrated the feasibility of using photogrammetric measurements to observe building movements during tunnelling, with the advantage of there being no need for access to the building being observed. The photogrammetric technique described could be used to measure displacements on other structures such as retaining walls and embankments. (Author/TRRL)
