Optimization Design for 3D Roadway Based on Space Analysis of GIS

## Excerpt

Traditional design of roadway was usually based on the method of CAD. That could not embody the geological features where the roadway was through, and also could not reflect the spatial relations of the roadways network. The design of roadway can be divided into two parts: the section and the axis. The goal is developing a design system with the function of optimization design for roadway in 3D environment. Geological models are established in 3D environment first. The roadway model is established by constructive solid geometry (CSG) method, and the relationships between roadway, axis and section are linked at the meaning time. It can perform the function of space analysis for the design of roadway in virtue of the GIS. The spatial relations between roadway and the coals seams, the faults and the constructed roadways can be considered, so it can implement the optimization design. For the roadways network existing crossing relationship, the calculation model and method are proposed to perform collision analysis accurately.
