The Analysis Of Elements Of Railway Line Selection And Application Of Line Design

Topographic map of the project design basis information, read topographic map information is the key to the project design. In order to achieve the above purpose, the railway line selection, design example, the use of the combined approach of attribute data and spatial data. Attribute data classification first impact factor in the design of the railway line selection, then the AHP the basis of data obtained through questionnaire method, and assignment of the railway line selection elements. Attribute data with spatial data using GIS tools will combine a series of spatial analysis and processing, and ultimately get the support of the railway line selection design three-dimensional images.As a result of the scientific basis of objective data, and data processing method, coupled by the GIS means the combination of spatial information and attribute information, get results, while comparing different line selection; On the other hand, in addition to support space alignment, can also be a general understanding of the new lines of the plane, longitudinal section, and to provide a basis for further design of the railway.
