Building response to tunnelling - case studies from construction of the Jubilee Line Extension, London. Volume 1: The project. Volume 2: Case studies (SP200)
The ability to predict the potential damage to buildings accurately and to have confidence in the chosen protective measures is of increasing importance for the viability of urban tunnelling. The Jubilee Line Extension Project (JLEP) presented a unique opportunity to capture reliable field measurements of the effects of tunnelling on a wide range of buildings. This book is the result of that work. Volume 1 describes the construction and protective works of the JLEP, the methods of settlement prediction and building damage assessment used on the project, and the objectives of the research. It provides accounts of the geology and historical development of the case study buildings (between Green Park and Canada Water stations of the JLE route) and full transcriptions of before-the-event and independent best-practice predictions of surface and at-depth ground movements for two greenfield sites and four buildings. These predictions were made specially for this research project. Volume 1 concludes with a contribution by Professor John Burland, which outlines the overall findings of the research to date.
Volume 2 presents, in their geographical sequence, 27 case studies, from Green Park in the west to London Bridge and then eastward to Canada Water station. These case studies include two instrumented greenfield sites and several examples of prestigious buildings in London’s West End that were protected by compensation grouting. The sites studied include Big Ben clock tower, the Treasury building, the Ritz Hotel and the RAC building, plus many commercial and residential properties. The case studies present descriptions of the buildings, the works that affected them and measurements made to record their response.This valuable and informative work was written by the experts who participated in the research, and will be of great interest to tunnelling and geotechnical engineers and all those who have an interest in this successful and interesting underground project.
