Eco-Friendly Civil Engineering:
Japan’s Nonframe Method

Aired: Nov. 26, 2021

A mountain slope collapsed behind a Japanese shrine with a thousand-year history. However, thanks to reinforcement work done afterwards, the shrine suffered minimal damage from a subsequent typhoon. A unique method in which long bolts were driven into the slope, points are covered with steel plates, and connected the steel plates with wires was utilized. This method is starting to be used worldwide.
