Simplified method for predicting building response to mechanized tunnelling in stiff clay
This paper investigates the application of an equivalent elastic beam model to predict the building displacements caused by mechanized tunnelling. A simplified Shear Slabs Portal Frame (SSPF) representation and 2D finite element analyses estimate the bending properties of buildings considering cross-sections transverse to the tunnel trajectory. The predictions are compared against measured building performance during tunneling through stiff London Clay, using an advanced soil model for non-linear ground stiffness. For twin Crossrail tunnels, reliable stuctural configurations and ground deformation data from Hyde Park enable accurate predictions of Avenfield House displacements. Similarly the study also examines the impacts of a single open-face shield tunnel (JLE project) on Westminster’sTreasury and ICE buildings. These cases involve greater uncertainties due to oblique tunnel angles and varying structural conditions, yet the analyses yield reasonable building settlement predictions. This research highlights the SSPF approach as an effective, simplified modeling tool.
