Presentation Transcript

  1. JOANNEUM RESEARCH Institute of Applied Geophysics – new Dam Project 2nd IMPACT Project Workshop Mo-i-Rana, Norway 12-13th September 2002 presented by: Rainer Morawetz INSTITUTE of Applied Geophysics

  2. Overview • Introduction to JOANNEUM RESEARCH and its Institute of Applied Geophysics • New Key-Project – „Dam Investigation Methods and Geotechnical Applications“ • Project Description • Geophysical Methods • Goals • Further Work

  3. Background - Company • JOANNEUM RESEARCH is Austria’s largest research organisation owned by a provincial government • Bridge between Research and Application • Applied R&D • Technology transfer • Promotion of future experts and executives

  4. Institute of Applied GeophysicsBackground –Institute of Applied Geophysics • Founded 1981 in co-operation with Montan University • Located in Leoben • Highly competent centre for development and application of geophysical methods • Institute offers full spectrum of geophysical methods • Staff: • Scientific staff: 11 • Technical and administrative staff: 4 • Students: 3 .... 4

  5. Institute of Applied Geophysics Main Research Fields • Seismic reflection for rock structure studies and reservoir characterisation • Borehole geophysics and petrophysics for complex rock characterisation • Geophysical methods for use in geotechnics, risk assessment and archaeology

  6. Institute of Applied GeophysicsMain Research Field 3 – Key Project: • „Development of Dam Investigation Methods and Geotechnical Applications“ • Extend the use of geophysical methods in geotechnical fields • Focus on development of a method for non-destructive, fast and effective investigation of dams and embankments • Milestones: • Literature Review • Test Measurements • Systematic Analysis of Methods

  7. Institute of Applied GeophysicsGeophysical Methods • Non-destructive • Repeatable • Ground characterisation using physical values

  8. Institute of Applied GeophysicsGeophysical Methods - Dams In general, better results gained by using a combination of methods

  9. Institute of Applied GeophysicsGoals • Identification and relevant geotechnical assessment of inhomogeneities using non-destructive techniques • Method for the economic investigation of long lengths of dam (eg. flood defence embankment) • Development of techniques for long-term monitoring

  10. Institute of Applied GeophysicsFurther Work • Implementation, trial, and refinement within scope of EU project and with industrial partners (particularly of mobile but economic investigation techniques suitable for long lengths of dam) • Development of techniques to derive absolute geotechnical values (eg. degree of saturation, shear strength…)

  11. JOANNEUM RESEARCH • Please talk to me in the breaks! • your opinion? • which geotechnical parameters are particularly • relevant to dams? • have you any data/ideas which may help us? INSTITUTE of Applied Geophysics
