Sydney Chapter

A Brief Introduction to the Monitoring of Urban Tunneling Projects

Dr David Bassett

In this short talk, Dr Bassett will set out a complete philosophy of planning, installing and assessing instrumented tunnelling projects in soft soils and hard rock ground. Approaches to observing and recording factors such as tunnel displacement, vertical settlement and horizontal strains will be discussed, along with the purpose, importance and correct procedure of implementing effective monitoring systems. The various parameters affecting any tunneling project will be explored, and effective methods to measure, analyse and react to these covered.

The aim is to give the attendee the tools needed to assess their own project and clearly appreciate the confidence and value a well structured monitoring program can provide.The presentation will be followed by a question time, in which Dr Bassett would be glad to answer any questions from the floor.
