In view of the planning and design for the new North-South metro linein Amsterdam an extensive research and development program was initiated on the impact of shield tunnelling on buildings (i.e.pile foundations) situated in the vicinity of the bored tunnels. Experimental research and several full-scale tests were performed in already planned tunnel projects, such as Second Heinoordtunnel, the Botlek railway tunnel and more recently the Sophia ralway tunnel. Simultaneously the resluts of the tests were used to validate a 3D FEM model. This paper describes the results of the research projects and gives an evaluation of the impact of sield tunneling on the bearing capacity of pile foundations and the ratio between suface settlements and pile settlements.
