1 MAGIC M ONITORING SYSTEMS TO A SSESS G EOTECHNICAL I NFRASTRUCTURE SUBJECTED TO C LIMATIC HAZARDS European Commission - FP7 Marie Curie Industry-Academia Partnerships and Pathways (IAPP) MID-TERM REVIEW MEETING

2 Fellow background MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Status: ER Recruiting institution: TUD – Delft University of Technology Recruitment period: – - The Hong Kong University of Science and Technology Behavior of saturated and unsaturated coarse widely graded soils under low confining pressures – Norwegian Geotechnical Institute (NGI) Thermo-Hydro-mechanical behaviour of soft soils

3 Work package addressed MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Tensiocone, WP2 UMS (SME) Tecno-Penta (TP-SME) Pessl Instrument (PESSL-SME) G Impuls (GI-SME) University of Strathclyde (USTRAT Université de Pau (UPPA)Delft University of Technology (DUT) High-Capacity Tensiometer, WP1 Data Control Software, WP4 Geophysical imaging of water content, WP3

4 Task(s) addressed MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Tasks T.2.3 Validation in calibration chamber. Test Tensiocone in calibration chamber. Test Tensiocone in the positive range as well as in the negative range in unsaturated silt samples. Test the response under dynamic conditions. T.5.3 Data collection and processing. Develop a web-platform for data access by all partners and process data for cross-check and modelling. Deliverables: D.2.3. Final design of tensiocone D.5.3. Comparative analysis of instrument response in the field

5 Real scale field test site: Leendert de Boerspolder Effect of climate: soil- atmosphere-vegetation interaction on the durability of the flood defence system (hydromechanical behaviour in saturated and unsatured conditions in soft clays and organic soils) Insight into complementary non invasive techniques for infrastructure (hydro- electrical behaviour) MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014

6 Laboratory Physical Modelling: Setting up a calibration chamber for the tensiocone Providing the necessary support for thermo-hydro- mechanical characterisation of the relevant soils MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014

7 Element testing: Saturated and unsaturated hydro-mechanical (and electrical) behaviour of organic soils and soft clays MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Triaxial testing of organic soils under saturated conditions Bring back into operation and upgrading of a triaxial device for unsaturated testing Upgrading an oedometer for electrical characterisation Characterising the hydraulic and the retention properties of organic and fibrous soils

8 Retention and hydraulic conductivity of organic soils MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Need for shrinkage curves to properly interpret the retention data Improving the procedures for saturation of the tensiometers in the Hyprop device. Characterising the hydraulic and the retention properties of organic and fibrous soils

9 Preliminary results on retention and hydraulic conductivity of organic soils MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014

10 MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Preliminary results on retention and hydraulic conductivity of organic soils

11 Outlook of future career MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 Benefits from MAGIC project Improve skills on field study and physical modelling and numerical analysis Improve knowledge and testing protocols for organic fibrous soils Linking thermo-electro-hydro-mechanical properties to innovative solutions for field instrumentation and monitoring Networking with academia and industry partners Improving scientific output both in terms of publications and in widening the scientific perspectives Bringing element testing into implementation in the practice: instrumentation, monitoring, assessing infrastructures
