Various slope protect systems are applied to the slope located around the major facility to maintain stability, and the applied these systems play an important role in protecting the structure by ensuring the safety of the slope. Reinforcement techniques ensure complete safety at the time of application to the slope, but over time, it may become difficult to secure safety. In particular, the deterioration of reinforcement systems may significantly reduce the stability of the slope. Therefore, it is necessary to secure the safety of the slope by defining the necessary items for maintenance of the protect systems and verifying them by the field expert. In this study, a group of experts were formed to determine these items and select their importance among them, and based on their data, the importance of each item was selected by Analytic Hierarchy Process (AHP). The selected items are expected to play an important role in the maintenance of reinforcement systems applied to the slope based on the survey items used by experts.
