Research on Shield Tunnel Three-Dimensional Modeling Method

Abstract

With the development of informational construction technology, the shield tunnel three-dimensional visualization has been more and more used. This paper proposes a modeling method of discrete space curve based on coordinates of shield line design, then calculate and generate shield tunneling model. The model data is stored in the form of triangular network. This method has fast modeling speed and low request of storage space, and is relatively easy to imply. It can be combined with GIS in fast simulation to improve work efficiency.
