A System for the analysis of precast tunnel segments during shield tunneling based BIM
Abstract: The paper addresses precast tunnel segments for the west line of the Hongmei South Road Tunnel to study how to monitor and record the structural behavior of precast tunnel segments. To aim this target, an intelligent system based BIM is designed and created. The system is divided into four layers. At the data capturing layer, the shield excavation information, the ground surface...

An Integrated Information Framework for Precast Tunnel Concrete Lining Segments Life-Cycle Management
Abstract: The quality of precast concrete lining segments is associated with the safe operation of the tunnel closely. Researchers and engineers require full life-cycle information of precast concrete lining segments so as to analyze tunnel defects, maintain tunnel segments and prolong the life of tunnel. This paper proposed an integrated information framework from the...

COBie+Interpretable and Complex Spatio-Temporal Relation Reasoning Network-Based Decision Analysis Method for the...
Abstract: With the in-depth research and application of BIM-based tunnel lifecycle management, how to effectively integrate and utilize the multi-source heterogeneous data generated in the management process has been a hot issue of concern. Although relevant researchers have proposed a multi-source heterogeneous data integration method based on IFC standard and ontology in the Architecture, Engineering,...

Online Multidimensional Time Series Anomaly Detection Algorithm based on Shield Construction
Abstract: The real-time anomaly detection is very important in the process of shield tunneling. The alarm for abnormal events can help the staff to make decisions quickly and ensure the engineering safety. However, the traditional methods of shield anomaly detection are mainly depended on analysing for one-dimensional time series one by one, so its accuracy is low, which cannot meet the actual...
