Estimation method of railway structure's unit price based on the theory of multi-dimensional space similarity
摘要
Abstract
The unit price of railway structure is an important index affecting its optimum distribution, and the accuracy of the estimation can provide an significant support to improve the intelligent level of the railway line selection design. However, the research in the field of unit price estimation is not mature enough .According to the corresponding attributes of the construction unit and cost information, the structure database of subgrade, bridge, tunnel and culvert was built based on GIS. By using the theory of multi-dimensional space similarity and powerful analysis function of GIS, attribute matching and unit price estimation of the new railway were be realized through the established information database. It can also be applied to the optimal distribution of the railway structure based on GIS.关键词
