摘　　要：对地质剖面图绘制技术的研究从20世纪90年代持续至今,其中主要的绘制方法有基于CAD进行绘制和采用GIS组件进行绘制.但是在这些研究中地质剖面图的绘制只依赖钻孔数据,由于钻孔数据稀疏不均,不能很好地反映断层等地质构造,因此在剖面图上对地质构造的定位和形态表达存在一定困难.本文基于GIS技术,融合基础地质数据、钻孔数据,实现了地质剖面图的自动绘制.在分析地质剖面图的几何特征的基础上,建立了地质剖面图的数据模型.根据断层的几何形态,实现了断层的绘制.The technology of drawing geologic section has been researched since the nineties of the twentieth century. Geologic section is mainly drawn by CAD technology and component GIS. But the researches only depend on bore data. Because the spatial distribution of bores is rare and uneven and bore data can＇ t reflect geological structures such as fault, it is difficult to locate the geologic structures and display the configuration of them on the geologic section. This paper fuses basic geography data and bore data based on GIS technology and automatically generates the geologic section. On the basis of analyzing the geometry characteristic of geologic section, the data model of section is built. The fault is drawn based on the geometry configuration.
