The Effect of Changing Slope Angle on Compression Test Results

By Karl W. Birkeland1, Edward Bair and Doug Chabot.

Conducting stability tests in avalanche terrain is inherently dangerous since it exposes the observer to the potential of being caught in an avalanche. Recent work shows that such exposure may be unnecessary since the results of extended column tests (ECTs) and propagation saw tests (PSTs) are largely independent of slope angle, allowing for data collection in safer locations.
