Abstract

 It is essential to employ the observational design and construCtion method to manage tunnel projects efficiently. The original tunnel design is immediately verified or modified based on the in-situ data sequentially obtained in the construction stage. This study proposes an integrated prediction system for geological conditions ahead of tunnel faces, which is composed of long-interval, middle-interval, and short-interval prediction subsystems. The applicability of those subsystems is verified with actual field data.
