石台杵岭隧道DEM建立及其应用

Founding DEM and Application of Chuling Tunnel's Region in Shitai

以1∶2000的AUTOCAD地形图为基础,在MAPGIS软件中,建立了石台杵岭隧道地区的数字高程模型(DEM),并应用该DEM生成了杵岭隧道纵剖面和计算了工程量。结果表明,以AU-TOCAD地形图为基础,建立DEM模型是简单可行的;应用DEM进行隧道纵剖面生成和工程方量计算是非常容易和精度较高的。根据以上结论,认为DEM引入到隧道和其他工程领域可行且非常有必要的。

This paper based on 1∶2000 AUTOCAD relief map,by using MAPGIS,found DEM of Chuling tunnel in SHITAI.Then,applying this DEM created vertical section of Chuling tunnel and counted earthwork.The results show that it found DEM based on the 1：2000 AUTOCAD relief map is easy and feasible.Creating vertical section of tunnel and counting earthwork is very easy and upper precision.According to above conclusion,this paper considered DEM importing tunnel and other engineering field is feasible and essential.
