Project Description

Summary: Monitoring of hang-slide movements with 10m long SOFO sensors installed on an unstable formation. Continuous measurements and remote monitoring

Clients: Verbundplan

Place: Eiblschrofen (Austria)

Period: 1999 - N/A

Installation: Riss / SMARTEC

Structure's short description: A sudden rock fall on July 10th 1999 revealed the potential danger of this formation that lies on top of an inhabited zone. A monitoring campaign was immediately started to insure the safety in the long term.

Aim of monitoring: Two 10m SOFO sensors are installed on the active fault of the rockslide. They are connected to a measurement station in the safe area where the movements are recorded at 5 minutes intervals

Number of sensor: 2

Main Results: The System was installed very rapidly and without the need of special protection for the cable that were simply laid on the ground. The sensors have been measuring for 2 years at 5 minutes intervals and have recorded the small movements with high resolution and reliability.
