Chelsea to Battersea tunnel surface settlements
16 August, 2019
Monitoring of ground surface movements induced by the construction of the Chelsea to Battersea Pipeline Tunnel project is presented as part of this case study. The surface settlements induced by the shaft construction have been analysed and compared with current methodologies and information from recent projects. Movements from excavation and construction of the tunnel are also analysed, and back-analysis of volume losses is presented. The authors are Veriuska Ortiz Lovera, geotechnical engineer, Mott MacDonald; Andrew Hejdner, project manager, Cadent Gas; James McCaffrey, construction manager, Skanska UK Construction; and Mohammad Arasteh, senior tunnel engineer, Mott MacDonald
