Fundamental Study on Development of a Shield Tunnel Product Model

Abstract

Although about half of the shield tunnel works done in the world exist in Japan, their product model has not been developed and detail construction related data are owned by engineers who worked at the construction sites. Considering the international contribution and business chances, in order to preserve the precious construction data for the future use, we decide to develop a product model for representing shield tunnel construction. As its first step, we investigated the characteristics of shield tunnels and developed a conceptual product model. Then, we implemented some part of the model by expanding IFC. We performed experiments of exchanging product model data with a 3D CAD system.
