基于GIS的高速铁路空间结构物布置方法研究
Research on Arrangement of Spatial Structures of High Speed Railway Based on GIS
摘要
Abstract
Many factors must be considered in the arrangement of railway spatial structures. Under the premise of saving capitals and, at the same time, determining a reasonable scheme of bridge, subgrade, tunnel scheme, DEM data management and spatial analysis functions in GIS system are employed to extract the ground elevation data under the condition of specific plane line position. The optimal layouts of subgrade, bridge and tunnel length on proposed slopes with minimum work amount and project cost are resolved by means of programming in consistence with design principles of high speed railway line cross-section. The calculation results satisfy the requirement of economical structure layout.关键词
