Study on immovable layer required to maintain the functional capability of anchor works for preventing landslide

Abstract

The anchor works are often used against slope failures and landslides. All tension power of the planned anchors should be surely reached to the immovable layer grounds to fix moving blocks of landslides. Therefore, it is necessary to secure the enough length from the slip surface to the head of the anchor root. In this study, we examined how to set up the needed length of the anchor in the immovable layer ground in consideration of various types or construction techniques of the anchors.
