The Application of Geophysics for TBM Tunnelling
by André Heim, Herrenknecht AG
Tuesday, 12 June 2018// 4.30 pm to 6.00 pm
Venue: CEE Seminar Room A (N1-B1b-06), NTU
School of Civil and Environmental Engineering, 50 Nanyang Avenue, Singapore 639798 63
The seminar will focus on the practical operation of geophysical prediction systems developed and used for application in mechanized tunnelling at Herrenknecht AG.
The different system types and their specific field of application in varying geologies as well as the main components and their integration into the tunnel boring machines (TBM) will be explained. The way the geophysical prediction systems are operated and detection possibilities will be mentioned, too. Project experiences with the systems will be presented.
The goal of using such geophysical prediction systems is to improve safety during tunnelling operation as well as making TBM advance more effective.
ABOUT THE SPEAKER:
After 5 years as a geologist in the fields of geological site supervision and documentation as well as geophysical measurement both on surface and underground large structures in Europe, André HEIM has been working as a Team Leader in the Department of Research & Development of the Business Unit Traffic Tunnelling of HERRENKNECHT AG for nearly 12 years now. He is in charge of development and operation of geophysical prediction systems suitable for mechanized tunnelling.
His experience includes the integration and usability of the different Herrenknecht geophysical prediction systems to the companies´ tunnel boring machines and application of those within the respective geological conditions such as hard rock and softground.
