Abstract
The paper focuses on recent developments in tunnelling and deep excavations in London and it draws on the experiences of the Jubilee Line Extension project which has just been completed. A brief historical review is given of the first tunnels and deep excavations undertaken in London some 150 years ago. Construction methods recently used for bored tunnelling include sprayed concrete linings and closed face pressurised tunnelling machines. Ground movements observed for these various tunnelling operations and for deep excavations are reviewed, and their effects on buildings are discussed. The most extensive protective measure used on the Jubilee Line Extension to control deformations and potential damage to historic buildings has been the relatively new technique of compensation grouting. Examples of its use are presented.
