Evaluation of settlement data collected during TBM excavation of a metro line of the Grand Paris Express

Résumé

Tunnelling under highly urbanized areas requires attention to risk assessment to guarantee the safety of all structures on the surface. Therefore, it is a necessity to measure all ground deformations and the parameters that have an influence on the surface settlement like ground conditions and tunnelling parameters such as the velocity of the TBM (Tunnel Boring Machine), the front pressure, etc. This article treats the case of line 15 South-West of the Grand Paris Express, consisting of 8 km of railway lines that are very well instrumented. The process of data collecting, cleaning and treatment is described in details. Some insight about the future work that will be done on these data is given.
