重量版青藏铁路数字路基仿真平台设计与开发

在青藏铁路建设和科研活动过程中对空间数据的管理、分析和使用,以及设计方案仿真评估、决策支持等方面有较高的要求,青藏铁路数字路基仿真平台轻量版系统无法满足需求.重量版系统着重于提供对分布式应用和充分的空间分析、仿真,以及空间决策支持功能的支持,系统建设以GIS技术为核心,结合遥感、全球定位系统(GPS)、虚拟现实和空间数据库等技术,在Microsoft.Net平台上开发而成.该系统不但能够对青藏铁路工程实验数据、观测数据以及各种专题数据和DEM数据等进行管理和维护,而且能够进行多时相、多维空间分析和表达,形成以基础地理数据为依托的数字路基仿真平台.

Design and Implement of Highweight Qinghai-Tibet Railway Digital Roadbed and Numerical Simulation Platform

Owing to the high requirement of Qinghai-Tibet railway constructing and scientific researching in the spatial data management,analysis and use,as well as the design scheme simulation and the decision-making support,the lightweight version of digital roadbed and simulation platform can't satisfy the demand.However,the highweight version of digital roadbed and simulation platform provides mainly a support on the distributed application,spatial analysis,simulation and spatial decision-making.The system is implemented on the Microsoft.Net platform with a GIS system as a kernel.Meanwhile the remote sensing,GPS,virtual reality and spatial database technology are used in the system construction.By integrating with several certain permafrost analysis models,the highweight version of digital roadbed and simulation platform is a powerful spatial analysis and decision-making support tool for the Qinghai-Tibet railway management.
