Abstract
A particular concern in ground-borne vibration is the extent to which the construction of a foundation affects the vibration field from an existing railway tunnel. This paper presents the results of a parametric study of this ‘added-pile effect’ using a numerical model that captures the dynamic behaviour of a single pile located near a circular tunnel, excited by vibration due to wheel-rail roughness. The added-pile effect is characterised for a range of scenarios in terms of the vertical pile-head insertion gain over the frequency range most associated with human perception. The results highlight two underlying mechanisms that determine the pile-head response and how these are governed primarily by the pile length, the soil-pile stiffness ratio, and the relative position of the pile and tunnel. It is also shown that the addition of a representative building, in the form of a semi-infinite column, does not significantly change the pile-head response.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported.
