At this lecture Dr Jamie Standing of Imperial College London will share key insights on the effect of new tunnelling projects on existing tunnels.

Urban expansion throughout the world has resulted in the need for many new tunnelling projects to provide adequate infrastructure for increasing populations.

Many cities already have comprehensive underground networks and so new tunnels have to be constructed in the close proximity of exisiting tunnels. There is always concern that ground deformations associated with new tunnel construction might adversely affect nearby existing tunnels and other subsurface assets and services.

In London the recently constructed Crossrail tunnels passed beneath numerous existing tunnels. This lecture will summarise key findings from a major research undertaken by Imperial College London and Crossrail, investigating the effect of tunnelling on existing tunnels using an interactive five path approach involving field monitoring, structural and soil testing and numerical analysis of segmental linings and field response.
