Abstract

Abstract

In order to realize the quantification and automatization on natural zoning for highway in China(NZHC), the spatial database structure of NZHC was designed from the concept, logic and physical aspects, the technology of spatial data engine was used, the spatial database was built based on the data storage and management function of large-scale relationship database management system, the difficult degree indices of highway engineering(DDIHE) were calculated by using multi-factor weight method based on the database. Analysis result shows that altitude, terrain slope, landform incision depth, landform incision density, hard rock coverage and vegetation coverage are main factors affecting DDIHE distribution, the map of DDIHE can visually reflect DDIHE in different regions from the view of physiognomy. Obviously, the establishment of the database realizes the quantification analysis mode of NZHC, solves the storage and management problem of mass spatial data.
