Technology of Preventing the Metro Tunnel Disaster Caused by Overhead Excavation in Underground Space

Abstract:

Rapid urbanization process brings large-scale excavation engineering and subway tunnel in city. Especially ,some excavations are just above the subway tunnel with almost no distance between the excavations and the subway. How to effectively reduce the deformation of tunnel becomes a subject worthy of researching. Based on the underground space in Zhujiang New Town which would be constructed cross metro tunnel, protecting technology has been proposed to guarantee the metro tunnel’s safety by application of time and space effect, which could benefit the following similar projects.
