Simulations for multi-level Analysis of interactions in Tunnelling based on the Building Information Modelling technology

1. Problem statement Building and construction information modelling for decision making during the life cycle of infrastructure projects is a vital means for the analysis of complex, integrated and multi-disciplinary systems. This project deals with the multi-level information modelling and simulation to assess the effects of underground construction, in particular mechanised tunnelling, onto existing infrastructure. The goal of the SATBIM project is to propose a multi-level simulation model for tunnel-structure interaction integrated in the framework of Building Information Modelling (BIM) to support engineering decisions during the project life cycle and to allow for the evaluation and minimisation of risks on existing infrastructure. SATBIM provides an integrated platform for structural analysis, visualization and optimization of the mechanized tunnelling process in early design stages. Thus, the output will have wide implications on underground construction technology and interaction with infrastructure, with high academic and industrial impact.

Objectives and overview The approach of the SATBIM project allows appraisal of different design alternatives at low computational costs by dynamically generating simulation models from BIM models at the required LoD for the specific problem to be solved. For example, minimising the overall risk of damage to buildings needs high LoD for structures, while estimating stresses in the tunnel structure needs high LoD for lining but low LoD for buildings is sufficient (see Figure 1 b). In order to address these requirements, the following Research Objectives (RO) are set: RO1: To develop a multi-level simulation model of tunnel-structure interaction integrated in the framework of BIM. RO2: To develop visualisation techniques within a BIM environment to enable condensed, intuitive and comprehensive representation of analysis results. RO3: To devise simulation-based meta models to enable real-time design decision support. RO4: To integrate optimisation tools within the integrated model to support the decision-making in the design and construction phase. RO5: To validate the proposed platform with real industry project data.
