Abstract: The design guidelines for snow bridges of Japan are based on 'Technical Guideline for Defense Structures in Avalanche Starting Zones' developed in Switzerland in 1961.There have been concerns about snow conditions changing as a result of the higher winter temperatures of recent years. Accordingly, snow pressure was premeasured at slopes that were measured in the previous examination about 30 years ago. The results show that the premeasured values of snow pressure do not exceed those of the design snow pressure but exceed the originally measured values. This is thought to be affected by the differences in snow depths and winter temperatures between the years of examinations.
