【摘要】 本文分析了国内外决策支持系统的发展和应用,初步探讨了将GIS应用于地区级路面典型结构决策支持系统的可行性,设计出利用GIS二次开发建立路面典型结构决策支持系统的结构框架,并提出了各项功能实现的具体方式,最终将干线公路路面典型结构决策支持系统集成到GIS平台中,将传统路面管理系统与基于GIS的路面典型结构决策支持系统相结合,根据公路管理者在实践中的具体要求,兼顾GIS界面与传统路面管理系统的优势,顺利实现基于GIS的路面典型结构决策支持系统的建立。本文研究与设计的要点着重在系统开发过程中,将干线公路路面典型结构决策支持系统数据库组建于GIS平台上,并结合数据库建立原则,对系统的空间数据库和属性数据库进行详细设计,并将两者进行连接建立路面典型结构管理数据库。利用C++Builder与MapObjects控件,Access数据库的联合开发,实现地图与数据的双向快速查询,并结合湖北省气候分区的特点,提出了一种新的工程数据分类方法,有效地解决了数值较为分散的指标对分类结果的干扰。通过引入各指标的权重,有效地解决了在具体的工程问题中,各指标的重要程度不同问题。此外还提出了对应不同的数据信息种类所占权重不同这一特定的条件下的空间内插方法,并解决在工程领域中已有点的数据通过空间的向量关系,插值出未知点的数据的问题。在上述研究的基础上成功开发了基于GIS的路面典型结构决策支持系统。更多还原

【Abstract】 This paper analyzes the application of GIS to the Pavement Decision Support System (PDSS)both at home and abroad, explores the feasibility of applying GIS to Local Typical Structure PDSS, works out the framework of Typical Structure PDSS based on GIS secondary development, as well as comes up with concrete implementation measures for such functions. This paper features the integration of Typical Structure PDSS for arterial highway with the GIS platform, the combination of traditional PMS with Typical Structure PDSS based on GIS and the successful realization of the establishment of GIS-oriented Typical Structure PDSS according to the concrete requirements of road keeper in due consideration of the advantages of both the GIS interface and traditional PMS.This project lays stress on establishing a Typical Structure PDSS database for arterial highway on the GIS platform in system development as well as designing out and connecting the spatial database and attributive database of the system in line with relevant database establishing principles to set up a Typical Structure PMS database. With the joint development of C++Builder, MapObjects and Access database, this project realizes the rapid two-way inquiry of map and data, and puts forward a new classification method for project data with regard to the climate division features of Hubei province, which effectively solves the problem of scattered data indexes’interference on the classification result, as well as the varied degree of importance of different indexes in concrete projects with the help of index weight. Moreover, this paper introduces the method of spatial interpolation under the special condition that different data information has different weight rates, and provides a solution to the interpolating of unidentified point data through identified data and the vector relation of space. Based upon the above-mentioned research, this paper develops successfully the GIS-oriented Typical Structure PDSS .更多还原
