IS-Cambridge | EPB-TBM Tunnel Under Internal Pressure: Assessment of Serviceability

June 27 - 29, 2022, 09:00 AM - 06:00 PM UTC+1

This technical talk will presents the numerical analysis of the structural forces acting on the tunnel rings using a riskoriented approach that considers the stochastic nature of materials, startigraphy and tunnel-ground interaction.

IS-Cambridge | A Risk Assessment of Downdrag Induced by Reconsolidation of Clays after Upwards Pipe Jacking

June 27 - 29, 2022, 09:00 AM - 06:00 PM UTC+1

In this presentation, a simple but powerful finite element model has been proposed to estimate the downdrag phenomena and the negative friction due to consolidation and creep, calibrating the soil profile using CPTu test.
