UNDERSTANDING GROUND MOVEMENTS CAUSED BY TUNNELLING

This paper is a short progress report on studies of ground movements where model tests in the laboratory have been related to ground movement surveys on tunnel schemes with different ground conditions and excavation techniques. The suitability of several theoretical and empirical prediction techniques is examined. Results from model tunnel tests show good prospects and similar tests are being used to check the validity of numerical solutions for the displacement field and final collapse parameters. Results from site measurements discussed include those made during construction of Moorfields Station Liverpool, the Fleet line at Green Park and Regent's Park London and several other sites including Chalk at Chinnor, Oxfordshire. Retrospective calculations have shown that numerical methods, given correct characteristics of ground properties, can produce accurate results. However because ground properties cannot be accurately defined before tunnelling, no true predictive method exists. The authors suggest that development of a combined theoretical/empirical approach will provide a solution. /TRRL/
