The 1st day of workshops, July 16, was rescheduled to be presented on July 17.
Workshop on Beyond Data Visualization – Data Analysis. 17th Tuesday afternoon.
WORKSHOP #2 – Practical aspects of field instrumentation
9h00 – 12h00.
The role of field performance measurements in risk assessment, control of natural geo-hazards and in the design, construction and operation of engineered facilities, has become a fundamental issue in today’s engineering practice, reinforcing the need for well implemented monitoring programs. In an attempt to address this growing need, the organizers of FMGM 2018 are holding a ½ day workshop on July 17th, the day before the symposium, for those interested in learning more about the practical aspects related to field instrumentation.
The workshop will focus on things to consider when:
- Planning an instrumentation program (Andrea Zattoni, CESI, Italy)
- Selecting, installing and troubleshooting
Piezometers (Tony Simmonds, Geokon Inc., USA)
Pressure cells (Giorgio Pezzetti, SMAK s.a.s., Italy)
Extensometers (Daniel Naterop, Sisgeo, Switzerland)
Inclinometers (Andrew Ridley, Geo-Observations Ltd., UK)
- Designing automatic data acquisition systems (Brent Randall, Campbell Scientific Inc., USA)
- Analyzing data (including sources of error) (Allen Marr, Geocomp, USA)
- Integrating classical geotechnical measurements with remote sense techniques (Paolo Mazzanti, NHAZCA, Italy)
The workshop will be presented by a team of recognized instrumentation specialists from around the world. It is designed to appeal to those wishing to increase their knowledge with respect to the practical aspects to be considered when designing and implementing optimal geotechnical instrumentation programs of any kind and magnitude.
WORKSHOP #3 – Beyond data visualization – Data Analysis
14h00 – 18h00.
New Trends in Data Visualization and Analytics
Dr Paolo Farina, Department of Earth Sciences, Università degli Studi di Firenze; Geoapp s.r.l., Academic spin off of the University of Florence
Alex Neuwirt, Canary Systems, Inc.
In recent years, the types and quantities of data that are available to help clients understand their operational and safety risks have increased tremendously. It was not that long ago that automated monitoring consisted of one or two types of instrumentation such as piezometers or inclinometers. Now data may be provided by automated total stations, TDR, differential GPS, ground based radar, satellite InSAR, laser scanners, vibration/seismic recorders, environmental sensors such as rainfall or air quality, among others. This has required improving data storage systems, improving the visualization of the data and the development of near real-time analytics to understand what the data mean. Numerous vendors have been able to provide these capabilities in their platforms leading to significant improvements in the value of the information being collected and ultimately significant improvements in the client’s ability to exploit more of the data to more effectively manage the risks they are exposed to. This workshop will present an overview of the advantages and challenges of data integration, a general discussion of the types of interfaces available, the use of near real-time data analytics to support the data interpretation thus providing more meaning to the data and allowing to forecast their future trends.
Integration of Data
Advantages/Challenges of Integration
General discussion of geo-spatial interfaces. 2D and 3D Interfaces
Understanding Data (Analytics)
General discussion of the importance of data analytics for data interpretation and data forecasting
Example: Rainfall data for the setup of early warning systems for shallow landslide prediction
Example: Micro-seismic activity forecasting
Example: Slope stability data interpretation and forecasting
Integration of new data sources
More advanced analytics for slope instabilities including volume estimation, run-out estimation, time of failure forecast, etc.
Use of artificial intelligence (AI) to identify more complex correlations.
Wireless Remote Condition Monitoring
Aidan Laimbeer / Arnaud Lancon/Graham Smith, Senceive Ltd.
Some wireless monitoring systems providers have now been firmly established over a decade, providing proven, robust and durable solutions for a full range of structural and geo-technical monitoring requirements. With long battery life of 10+ years and a wide variety of supported sensors, comprehensive monitoring and analysis solutions can be simply and quickly deployed.
Three case studies illustrating the ease, flexibility and effectiveness of a comprehensive wireless monitoring system are presented.
The Toowoomba Second Range Crossing is the largest Australian Government funding commitment to a single road project in Queensland’s history. One of the main engineering features of the project is an 800m long bridge that will negotiate the steep terrain of the range. The Senceive system was used to monitor the Brisbane-Toowoomba Railway track bed, earthworks and retaining walls for its surroundings during early earthwork, piling and blasting activity to provide comfort that trains could continue operating whilst major works took place nearby.
Storm Eva caused cracks appeared on the carriageway of the historic Grade II listed Linton Bridge and there was significant bridge deck settlement of up to 200mm due to scouring at the footings caused by river flooding. The bridge was closed for over 9 months to road and foot traffic. Due to safety issues and cost, it was difficult to find a way to continuously and effectively monitor the movement of the bridge manually. Wireless sensors were installed within three hours on each parapet wall and monitored settlement on the bridge remotely using solar powered gateways, to sub 1mm resolution. Continued settlement was seen, and major remedial works carried out and it has now re-opened.
Just outside London, on the busy “commuter belt” rail lines, an unstable railway embankment was being monitored with a combination of high precision tri-axial tilt sensors, complemented with mains power free, wireless cameras that can provide triggered images, activated by the tilt sensors, to show if material has fallen on the track. If necessary, “flight controllers” might stop or slow trains. In this case, a significant landslip was indeed detected by the sensors, and its progress was recorded by the cameras providing a clear visualization of the slip. But by using the cameras, no engineer or surveyor needed to visit site, as it was not deemed serious enough and the rapid decision was taken to not stop trains.
