MANAGING IMPACTS OF GROUND MOVEMENT IN URBAN TUNNELLING

This paper considers the many technical and organisational challenges associated with constructing a deep cut-and-cover tunnel for the Central Artery/Tunnel project through the congested centre of Boston, USA. The causes of ground movement during excavation are discussed and methods of predicting deformation reviewed. In the Boston project the semi-empirical method was used to screen for trouble areas which were then studied further using finite element analysis. Construction methods to reduce soil movement are considered. In the Boston project it was necessary to assess a considerable number of historical structures. Details are given of the stringent construction criteria set and instrumentation used. Other aspects discussed include design accountability and working with the owners of existing structures.
