The application example of the falling rock protection reinforcement soil retaining wall in the Mt. Fuji falling rock disaster

In July, 2009, a falling rock disaster occurred at Mt. Fuji the fifth stage. Though this disaster outbreak slope is a slow incline, a falling rock arrives at the suffering point and develops into a serious disaster. After disaster outbreak, I simulated a falling rock course based on a field work, and it was executed the work a falling rock protection reinforcement soil retaining wall mechanic (a Geo-Rock wall method of construction) which I could cope with a high energy falling rock as the measures mechanic that could cope with an assumed falling rock scale in future, and could consider a scene. I report the example of the real falling rock protection reinforcement soil retaining wall mechanic executed the work on the basis of design procedures from investigation of the disaster outbreak mechanism to the measures mechanic choice in this article.
