Abstract:

The incidence of icefall is one of the most underrepresented and likely underappreciated of all the natural hazards. Falling pieces of ice are subject to melting and sublimation, and evidence of such events may be gone in a matter of days or even hours. There is very little existing research and engineering design criteria relative to icefall hazard mitigation. Alaska DOT&PF is undertaking research aimed at better understanding icefall hazards and eventually quantifying risk of impact along state highways, in an effort to mitigate icefall hazards. The research project was broken down into two (initial) distinct phases – Phase No. 1 Literature Review (completed 28 February 2016) and Phase No. 2 site-specific studies. This research report summarizes the results of Phase No. 2, and details the results of onsite studies and preliminary icefall hazard technical evaluations and risk assessments. This report also provides key icefall predictive indicators and a range of recommended mitigation solutions worthy of further consideration
