Sammendrag
The Ryggfonn avalanche path has been instrumented to measure: deflections on a 6 m high steel mast mounted at top of the test embankment by means of weldable strain gauges; wind speed of powder snow fronts by means of a three direciton propeller based wind speed sensor; snow pressure forces on an 18 cm
diameter strain gauge based load cell mounted at top of the test embankment; axial tension in three high tension cables crossing the avalanche path by means of strain gauge based in-line load cells; snow pressure forces acting upon a 4.5 m high concrete structure by means of three strain gauge based load cells totally covering the wall facing the avalanche; vertical vibration velocity by means of a seismometer mounted at the concrete structure
