Construction Simulation of Large Diameter TBM Tunnelling in a Sharp Curve Alignment in Soft Clay Using 3D Numerical...
Abstract: This paper presented a case study on the numerical simulation for construction of large dimeter TBM tunnelling in a sharp curve alignment. It took Shanghai North Crossing Channel as a case to analyse the tunnel settlement and alignment offset during the construction. A notable feature and difficulty in this project was that larger-diameter tunnel (15.56m outer diameter) run in soft clay with a...

Damage cause and renovation of base structure of a railway tunnel at slightly-dipping interbedding rocks: a case study
Abstract: The Y.D. Tunnel, designed with double block ballastless tracks in Southwest China was excavated at low-medium thick slightly-dipping interbedding rock mass of medium-weathered mudstone and sandstone. A high uplift appeared in the tunnel floor within the region of K208+620~+629 after the tunnel was put into service, seriously influencing the railway operation. In-situ stress was measured;...

Impact and Back Analysis of Deep Excavation on Existing MRT Line under Complex Surrounding Conditions
Abstract: The North-Cross Expressway project in Shanghai were introduced, involving deep excavation above existing Mass Rapid Transit (MRT) Line 13 and corresponding impacts under the complex surrounding conditions. Displacements of the MRT tunnel and retaining walls were analysed in the Plaxis software by using hardening soil model to predict the soil displacement. In additional, backanalysis based on...
