摘要
阐述了GIS技术在长江流域岩土工程中的部分应用状况,主要是分析三峡地区滑坡、堤防监测和水土保持相关领域工程应用情况。GIS系统能够用来收集、管理和分析空间数据及其相关属性,具有2个显著的特征:(1)不仅可以像传统的数据库管理系统那样管理数字和文字信息,而且可以管理空间图形信息;(2)可利用各种空间分析的方法对多种空间信息进行综合分析,解决空间实体之间的相互关系,分析和处理在一定地理区域内分布的各种现象和过程。正是由于GIS这种对多种空间信息和属性数据的处理和分析能力,使得研究者可以采用一种新的综合方法研究、解决地学领域内的各种问题。目前,GIS对多源地学信息进行综合分析,广泛应用于地质、环境等研究领域。遥测系统的发展使得大尺度空间基础地理信息数据获取和海量数据处理成为可能,通过数据转换、数据嵌合和叠置处理,信息通过光纤传输,专题图层可在GIS专业软件平台上提取、分类和套合。利用计算机专业地理信息系统软件平台可以对三峡地区滑坡分析、水土保持、堤防监测等水利相关领域课题进行综合研究。
The application of geographic information system （GIS） technology to geotechnical engineering in Yangtze river basin is studied. GIS technology has been put into use in the field of landslide analysis, soil and water conservation, and levee construction monitoring. GIS is a set of systems which can be used to gather, manage, and analyze spatial data and the related attribute properties. GIS have two remarkable features .as follows： （1） it can manage data and literal information like traditional database data base management system （DBMS）, and it can manage the spatial graphic data; and （2） the complicated spatial data can be analyzed by synthesis method with various of spatial analysis modules in the GIS software platform. Consequently, the interdependence of the spatial items has been established. The analyses of nature phenomena and process in some specific geographic areas are gained, and certain spatial relationship has been proposed, which enables researchers to employ a new synthetical method to solve various problems in geographic field. Presently, GIS technology is introduced in many fields and engineering in Yangtze river basin such as geotechnics, environmental science, water resources planning, river and forestry conservation and so on. With the development of remote measurement technology, it is possible to build on basic spatial geodata database on large scale. By implementing data conversion, data mosaic, overlap processing, GIS can carry out mass data processing and convey the useful information by fiber-optic transmission system. As a result, any special map which will be used in the engineering can be extracted, classified and combined on the computer aided software platform of professional geographic information system.
