The method of 3D modeling for tunnel engineering and the simulation technology of its seamless excavating
Abstract：A new method of tunnel engineering seamless excavating was put forward based on the deficiency of previous studies.In this method,the geological model was created by generalized tri-prism（GTP） volume based on the smallest vertex identifier（SVID）,this model can convert into the B-Rep model made up of triangles.The model of tunnel was created by section method;the model was also formed by triangles.The simulation and special analysis of tunnel engineering seamless excavating was realized by optimizing Local Hierarchical Intersection（LHI） algorithm between triangles of the geological model and tunnel engineering model.The application case shows that this method is fast and effective,and it can satisfy the need of design and special analysis for tunnel engineering of digital mine.
