Response of Buildings Supported on Shallow Footings to Tunnelling Induced Ground Movements: A Case Study of Selected Buildings at Bond Street Station.

Summary

This paper evaluates the influence of Crossrail tunnelling works on selected buildings at Bond Street. The monitoring results of ground and building deformation and damage observed during the works are analysed and compared to those developed using the analytical and empirical methods.

The monitoring results showed evidence that changes in building use, land use and disturbance of ground, influenced the response of the building to the tunnelling works. The increased rates of settlement in areas where changes in land use are suspected are discussed in conjunction with the observed building response.

Feedback on the level of damage, specific problems encountered, assessment methodology and the appropriateness of the applied mitigation measure will be provided, along with recommendations for similar future cases.
