An integrated platform for design and numerical analysis of shield tunnelling processes on different levels of detail

Abstract

Building and construction information modelling for decision making during the life cycle of infrastructure projects are vital tools for the analysis of complex, integrated, multidisciplinary systems. The traditional design process is cumbersome and involves significant manual, time-consuming preparation and analysis as well as significant computational resources. To ensure a seamless workflow during the design and analysis and to minimise the computation time, we propose a novel concept of multilevel numerical simulations, enabling the modelling on different Levels of Detail (LoDs) for each physical component, process information, and analysis type. In this paper, we present SATBIM, an integrated platform for information modelling, structural analysis and visualisation of the mechanised tunnelling process for design support. Based on a multi-level integrated parametric tunnel information model, numerical models for each component on different LoDs are developed, considering proper geometric as well as material representation, interfaces and the representation of the construction process. Our fully automatic modeller for arbitrary tunnel alignments provides a high degree of automation for the generation, the setup and the execution of the simulation model, connecting the multi-level information model with the open-source simulation software KRATOS. The software of SATBIM is organized in a modular way in order to offer high flexibility not only for further extensions, but also for adaptation to future improvements of the simulation software. The SATBIM platform enables practical, yet flexible and user-friendly generation of the tunnel structure for arbitrary alignments on different LoDs, supporting the design process and providing an insight into soil-structure interactions during construction.

Building Information Modelling in mechanised shield tunnelling – A practitioner's outlook to the near future

“…The SatBim framework [15] is a comprehensive concept for the integration of multiscale model representations into a BIM. This concentrates particularly on the geomet ricalsemantic modelling of the mechanised shield drive in a form suitable for direct use in numerical simulations.…”

“…Mit dem SatBimFramework [15] wurde ein umfassendes Konzept zur Einbindung mehrskaliger Modellrepräsenta tionen in ein BIM entwickelt. Hier liegt der Fokus insbe sondere in der geometrischsemantischen Modellierung des maschinellen Schildvortriebs in einer Form, die sich für den direkten Einsatz in numerischen Simulationen eignet.…”

A Hybrid Data Mining Method for Tunnel Engineering Based on Real-Time Monitoring Data From Tunnel Boring Machines

“…have been built to achieve effective data management [3], [4], including automatic data collection, storage and visualization. However, manual analysis falls short of consistent standards and poses risks for tunnel construction.…”

“…(3) The performance of TBM is evaluated by ANN models and abnormal conditions can be discovered by comparing the evaluation value with actual value. (4) Improvements have been made to existed DM algorithms based on TBM characteristics to improve performance. (5) The three DM algorithms are not only designed to solve single problems, they are also combined to form a hybrid DM framework to improve data mining process.…”

Improving Applicability for Information Model of an IFC-Based Steel Bridge in the Design Phase Using Functional Meanings of Bridge Components

“…The improvement of the applicability based on the information model ensures interoperability throughout the lifecycle phases or information reusability between different application fields using one model. Examples of the effort to improve interoperability using an open data schema to utilize the BIM generated in the design or construction phase are to apply the BIM in the facility management (FM) phase [6,7], or reuse it as a structural analysis model [8][9][10]. In other words, to reuse model data and ensure interoperability between software packages, the use of the information model generated based on the open standard data schema marks the beginning of the process.…”
