In June of the 7th year of Reiwa, the "Technical Standards for Road Earthworks Structures" were revised, and an example of setting limit states for rockfall protection facilities and verifying that these states are not exceeded was presented. Based on this, I will discuss the setting of limit states for high energy absorption pocket-type rockfall protection nets and the methods for verifying that the condition of the protection net does not exceed these limit states.
