SNOWSHED LOCATION AND DESIGN

LOCATION AND DESIGN OF SNOWSHEDS FOR AVALANCHE DEFENSE MUST BE BASED ON CAREFUL STUDIES OF TERRAIN AND OF AVALANCHE FREQUENCY AND SIZE. PRELIMINARY OBSERVATION AT SITES OF PLANNED AVALANCHE DEFENSE WORK IS OUTLINED. FACTORS THAT MUST BE CONSIDERED IN STRUCTURAL DESIGN OF SNOWSHEDS ARE' LOADS BY MOVING AVALANCHES AND BY DEPOSITED SNOW, LENGTH OF THE SHED, LIGHTING, DRAINAGE, AND MAINTENANCE. SHED LENGTH CAN BE REDUCED BY DAMS AND WALLS BUILT PARALLEL TO THE DIRECTION OF THE AVALANCHES. THESE FACTORS ARE DESCRIBED WITH REFERENCE TO DESIGN AND PERFORMANCE OF SNOWSHEDS FOR THE TRANS-CANADA HIGHWAY AT ROGERS PASS, BRITISH COLUMBIA. LONG, CONTINUOUS SNOWSHEDS COVERING MORE THAN ONE AVALANCHE TRACK WERE FOUND TO BE MORE ADVANTAGEOUS THAN A NUMBER OF SHORT SHEDS WITH SHORT, OPEN SPACES BETWEEN. /AUTHOR/
