【摘要】 铁路勘测一体化设计是以数字化信息为基础，以计算机应用技术接通勘测设计全过程为主要特征的新的生产作业模式。所以，该系统应将使用各种勘察手段所采集的铁路线路及其相关的地形、地理、地质、水文等资料加工成数字化信息，通过接口界面进行信息处理并传输到工程数据库中。在一体化新的作业模式下，勘测设计的全过程可以理解为对一般数字化信息流的采集、加工和扩充的过程。外业的勘测和勘探资料是这股数字化信息流的源头，各专业的设计工作是对信息流的加工和扩充。最终完成的数字化信息就是设计成果和归档资料。本文主要是基于铁路勘测一体化辅助设计的基本原理，应用计算机技术、数字图像处理技术、数据库技术与地理信息系统等多学科的理论和方法，结合Microsoft公司提供的面向对象的可视化编程语言Visual Basic 6.0与Autodesk公司提供的图形数字化软件AutoCAD2002，探讨铁路勘测设计一体化辅助设计的全过程。本文主要解决的问题有：1．建立了基于原始离散点和规则格网点数据的数字地面模型(DTM)。2．建立了基于中小型的关系型数据库(RDBMS)管理系统的勘测设计工程数据库。3．利用CAD系统来实现GIS的主要功能，完成对图形及其属性的查询与分析。4．在分析传统横断面测量方法的基础上，在独立坐标系的约定下，采用坐标平移的方法将全站仪坐标测量引入铁路横断面测量，内业数据处理采用VB6.0与图形软件AutoCAD2002相结合，成功实现了横断面测量的数据自动化成图。5．从软件工程思想出发，结合可视化编程语言Visum Basic6.0与图形软件AutoCAD2002，设计开发了铁路勘测一体化辅助设计的软件。更多还原

【Abstract】 The design of Integrative in the survey of railway is a new work mode, which is based on digital information and is charactered with applying computer technology to all the survey and design course hence, The system should transform the data which include the railway line, geomorphology, geography, geologic and hydrology to digital information, then deal with the information in the interface and transmit it to the engineering database. In the new Integrative work mode, all the survey and design course can be considered as a course of gathering, processing and extending the digital information. The headstream of the digital information stream is the surveying and prospecting data in the field survey, the digital information stream are processed and extended by all the professional designer. The final digital information is the production and pigeonhole data.The paper is Mainly based on the basic principle of Integrative thesurvey and design of railway, It takes full applications of theorys andtechniques such as computer technology, digital image processingtechnology, database technology and GIS, at the same time,it combinedVisual Basic 6.0 of Object-Oriented Language and AutoCAD2002 ofFigure Software .Finally, It discusses the full process of the survey anddesign of Integrative. This paper mainly solves some problems as follow:1.establish DTM which are based on original discrete points andregular gridding points data.2.establish survey and design engineering database which are basedon the Middle-Small Relative DataBase Management System.3.use CAD to realize the main function of GIS and complete theinquiry and analysis of the figures and their attributes.4.Based on the analysis of the methods of traditional transect survey, coordinates survey of total station which takes use of coordinates shift under the control of independent reference frame is introduced into railway transect survey. Visual Basic 6.0 banding together with figure software AutoCAD 2002 in the indoor work successfully implements auto-Mapping of data in the transect survey.5.Based on the software engineering thoughts, combined Visual Basic 6.0 and AutoCAD 2002, we design an assistant software integrative of the survey of railway.更多还原
