青藏铁路路基稳定性模型的GIS集成工作环境应用研究

为了发挥GIS在青藏铁路冻土路基稳定性研究中有力的支持作用,在已经建成的青藏铁路数字路基GIS平台的基础上,探讨了一种基于过程集成模式的模型与GIS集成方法,研究建立专业冻土路基模型与GIS平台集成的可视化"模型GIS集成工作环境",研究重点为专业冻土路基稳定性模型模块在此"模型GIS集成工作环境"中的集成技术手段、模型管理模式以及模型调用模式.作为研究成果,实现了一个实用原型系统.

Research of GIS Integration Working Environment of Embankment Stability Models for Qinghai-Tibetan Railway

GIS can support the frozen soil embankment stability research of Qinghai-Tibet Railway powerfully.On the base of Qinghai-Tibet Digital Embankment GIS Platform,which has been built already,a GIS-based visualization railway embankment stability model integration working environment is trying to develop for integration of professional frozen soil embankment models and GIS environment by the approach of Process Integration Pattern.The keys of the Model Integration Working Environment is to research the integrating technical methods,the patterns of model management as well as the pattern of model invoke.As the research result,an applicative prototype system,named Model and GIS Integrated Working Environment,has been established,of which the key functions include model working environment,spatial data support,visualization,as well as the spatial analysis support.
