Održano predavanje Prof. Norikazu Shimizu, Yamaguchi University

 

 

U subotu, 19. svibnja 2018., u prostorijama Hrvatskog geološkog instituta održano je predavanje Prof. Norikazu Shimizu.
Prof. Shimizu je potpredsjednik International Society of Rock Mevchanics (ISRM) i ugledni japanski znanstvenik. O njegovom statusu najbolje govori državna nagrada za spriječavanja katastrofa koju mu je prošle godine osobno uručio japanski premijer Shinzo Abe. Razvio je metodologiju praćenje pomaka površine terena koristeći radarske satelitske snimke. Ova tehnika omogućava mjerenje pomaka bez postavljanja repera ili antena na površini terena. Koristeći ovu tehniku izmjereno je slijeganja Tuzle uzrokovano eksploatacijom soli kao i pomaci na klizištu Kostanjek u Zagrebu, a na predavanju (prostorije HGI-a, Sachsova 2, 19.05.2018.) je izložio primjenjenu metodologiju i rezultate za ove lokacije. Nakon predavanja je održana kraća diskusija i obilazak klizišta Kostanjek u Podsusedu.

Radni naslov predavanja & kratki sažetak:

Practical applications of displacement monitoring using satellite technology to landslides, land subsidence, and dam deformation- including case studies in Croatia and Bosnia and Herzegovina

Summary:
Monitoring is important for assessing the stability of natural slopes and manmade structures, and for confirming the validity of the design and countermeasure works. In addition, it is also useful for predicting risks, for managing safe operations, and for reducing project costs in Geotechnical Engineering.
There are various types of instruments for taking field measurements: extensometers, inclinometers, etc. Although they are useful, these instruments may not be adequate for monitoring large slopes or extensive areas because they can only be applied to limited areas. The satellite technologies, GPS and DInSAR, can be applied to monitor the displacement of the ground and structure surfaces over large areas.
This lecture will explain how such modern technologies work on various geotechnical issues, i.e. landslides, subsidence and dam deformation, through practical applications including case studies in Croatia, Bosnia and Herzegovina, and some other countries.
