3D Modeling of Tunnel Engineering based on Geological Body

3D geological modeling has involved the complexity of two aspects: data and models. 3D geological modeling of the tunnel project real environment needs to fully abstract data, the entity model needs to be decomposed into the geometric model, property model, and the relationship of geological structure between tunnel engineering geological body and the surrounding geological body needs to know. The paper has researched and analyzed the process and method of the tunnel engineering geological body modeling, and the conclusion has shown that the 3D modeling based on the overall tunnel engineering geological body is more suitable for the real environment; its effect of modeling is obviously superior to the simple superposition of the general geometric modeling and property modeling.
