Abstract

Abstract:

Based on 2302 trough tunnel of some mine in Shan-Bei mining area, optimized it’s section figure and supporting programme by FLAC numerical simulation software and the theory of“Self-stabilized Hidden Arch”, so that it can be in favor of the deformation of 2302 trough tunnel. Designed the monitoring programme and analyzed some supporting datas.The results show that the optimization section figure of 2302 trough tunnel and it’s supporting programme are reasonable and feasible, and met it’s safety.

Key words: trough tunnel, FLAC simulation, Self-stabilized Hidden Arch, f optimization, monitoring
