Design Model of Residual Water Pressure on the Tunnels act as Drains
Abstract: Deep tunnels or subsea tunnels are generally undertaking considerably high water pressure, and are required to flow into the tunnel to reduce the water pressure. To avoid structural effect, tunnels under high water pressure exceeding 6 bar are commonly recommended to construct as a drained tunnel. However, even the tunnel is designed as drained, tunnel linings take water pressure which is...

FEM based Estimation of EDZ under TBM induced Vibration
Abstract: Excavation-induced vibration is one of the main concerns in urban underground construction. The vibration during excavation can be the cause of ground disturbance, or even damage the soil structure which may have negative effect to the stability of structures nearby, and to the surrounding ground. To overcome these situations, the application of mechanical excavation using tunnel boring machine...

Importance of face pressure and tail void grouting on numerical modeling of shield TBM tunneling through soft ground...
Abstract: Shield tunneling is now becoming a general trend in tunnel excavation. Despite the growing importance of shield tunneling, a prevalent standard for its numerical analysis has not been established yet, due to difficulty in appropriate implementation of face pressure, tail void grouting, and continuous excavation steps during shield TBM tunneling. Since there are various empirical methods to...
