Effect of building stiffness on tunnelling-induced ground movement
The progressive response of two-three storey masonry buildings to bored tunnelling on the Jubilee Line Extension in London, GB, is investigated in order to determine the effect of building stiffness on tunnelling-induced ground movement. The masonry buildings, at Moodkee Street and Keetons Estate, were affected by tunnelling with earth pressure balance machines on Contract 105 of the Jubilee Line Extension. Bending deformations and axial strain induced in these structures are compared to greenfield ground deformations and strain in order to infer the effect of building stiffness. The modifying influence of the stiffness of these buildings on ground movement is interpreted using the Potts and Addenbrooke method, which is based on a series of finite element analyses. The inferred building stiffness that can be used for design purposes with the Potts and Addenbrooke method is compared to an estimation for a Class A prediction exercise using the same method. As a result an alternative approach is proposed for estimating the relative bending stiffness of masonry structures for future use with the Potts and Addenbrooke method when making simple predictions.
