New Hydro-mechanical Tunnel Excavation Method using an Abrasive Waterjet System
Abstract: Hard rock excavation in urban areas is quite a challenge owing to the excavation vibration level and the necessity of rapid excavations. Conventional blasting methods and/or the use of a tunnel boring machine (TBM) are broadly utilized at present. However, conventional blasting methods cannot prevent the propagation of blasting vibration, while the TBM method is not appropriate for mixed ground...

Numerical Analysis on Settlement Behavior of Shallow Box Tunnel Widening
Abstract: Utility tunnels jointly accommodate various infrastructure such as electric and communication lines, gas, water and sewage pipes in the ground, so the aesthetics of urban areas are improved and traffic flows can be well maintained. In Korea, Utility tunnels was first installed in 1978 to supply electric power, water and heating in Seoul. After several repairs, they are still being used. But...

Tunnel Face Ahead Prediction on TBM using Tunnel Electrical Resistivity Prospecting System (TEPS)
Abstract: Construction of underground structures, such as cable tunnels and sewage tunnels, is increasing with the development of cities. Tunnelling methods for the construction of underground structures are divided into conventional methods (such as a drill and blasting method) and mechanized methods (such as the Tunnel Boring Method, TBM). Conventional methods cause relatively high noise and vibration...
