Description
Summary:With respect to the force of impact of a snow avalanche when it strikes a structure, there seems to be very little real experimental evidence as regards real avalanches. Before the war, Inazumi and others of the Railroad Research Laboratory undertook some experiments in the vicinity of Tsuchitaru on the Joetsu Line. The experiment consisted of sliding a block of snow down an inclined board and measuring the force of impact by means of displacement of a spring-loaded stop, and the conclusion was that snow could be treated as a completely inelastic material. Here results of a model experiment performed at Itaya on the Ou Main Line are reported, and a field study conducted on the Taishihoku Line is discussed.
