This report covers work completed during the period October 1976 to September 1977 under a research contract between the Transport and Road Research Laboratory and the Cambridge University Engineering Department for investigations into the behaviour of tunnels and tunnel linings in soft ground. The work carried out on the development of finite element techniques is covered in detail in a supplementary report by Gunn, MJ which should be read in conjunction with this one. A brief description of the experimental and theoretical work undertaken is given. The work described is primarily concerned with the effects during tunnel construction and therefore deformations and stability of unlined tunnels under undrained conditions were being studied. Some of the other experimental work described deals with: model tunnel headings in clay; behaviour of model tunnels in soft clay; centrifugal model tests and a comparison is made of behaviour of model tunnels under surface and gravity loading. /TRRL/
