BIM-to-FEM: Incorporating Numerical Simulations into BIM Concepts with Application to Real Tunneling Projects
Abstract: Finite element (FE) simulations are an integral element of the planning and design process for mechanized tunneling projects. The models needed for these simulations are typically manually generated using 2D-CAD drawings, which is a laborious and time-consuming process. Recent trends incorporating Building Information Modeling (BIM) concepts offer opportunities to simplify this process by using...

BIM-to-FEM: Incorporating Numerical Simulations into BIM Concepts with Application to the Wehrhahn-Line Metro in...
Abstract: In current tunneling practice, it is recommend to employ Finite Element (FE) simulations in order to ensure a high degree of safety and quality. As such, FE models form an integral element in the planning and the design process of mechanized tunneling projects. These models needed for the simulations are oftentime consuming to construct and require data from many different sources. However,as...

Computational Modeling for Joint Rotations of Segmental Lining in Mechanized Tunneling
Abstract: Mechanized tunneling presents a widely used tunneling method that is particularly effective in soft ground conditions and in the presence of ground water. It involves various complex processes and interactions, between both the surrounding soil medium and the shield machine during the TBM advancement and between the soil and tunnel lining via grouting mortar. Tunnel lining forms the permanent...

Modeling and optimization of ground freezing in tunneling
Abstract: In geotechnical applications of the artificial ground freezing (AGF) technique, safe and economic design and execution of the method require a reliable prediction of the coupled thermo-hydro-mechanical behaviour of soils subjected to freezing. In the context of thermo-poro-plasticity, a three-phase Finite Element model of freezing soils is presented, considering solid particles, liquid water...
