Analysis of the field monitoring data on soil movements and adjacent building settlement due to shield tunnelling

摘要

Purpose The shield tunnels closely constructed near the foundations have an inevitable influence on the structures, even results in the large settlement or uplift of the structures. Design/methodology/approach The comparison of structural deformation of three different foundations is presented based on the field monitoring data. Findings Shield tunnelling parameters vary for the different types of foundations. For the long pile foundations, the recommended speed is 3 to 4 cm/min, the grouting pressure is about 0.3 MPa and the grouting rate ranges from 150 to 180. Originality/value The study based on the field monitoring data is rarely reported, especially the topic about the structural deformation of different types of the foundations.
