摘 要 地质剖面图和柱状图是整个地质工作成果的基础和先导图件，是地质工程师经常性绘制的图件。 传统的绘制方法是制图师手工进行绘制，上世纪后期GIS理论发展成熟，人们开始采用交互式的图形矢量手段进行地质图件的编绘，但随着计算机技术的不断发展，追求计算机自动生成地质剖面图和柱状图已水到渠成。 本论文旨在达到利用计算机自动生成地质剖面图和柱状图，而且通过采用合理的设计方法，满足多种类剖面图和柱状图的自动生成，在收集多个矿区基础钻探资料的基础上，建立了矿区地质数据库作为原始数据库，利用面向对象的方法设计出剖面图和柱状图自动生成模块的数据模型和方法，采用Visual C++作为编程语言实现数据的调用及图形的自动生成。 本次论文共计完成代码1万余行，设计了一小型CAD系统，除了满足基本图形元素的绘制编辑之外，以地质剖面图和柱状图自动生成为主要功能模块，界面友好，设计合理，能自动生成地质剖面图和柱状图，可向煤矿系统推广使用，而且采用面向对象方法使得后续功能模块的添加变得极为方便，本论文中提出了处理地质剖面图生成过程中地层层位协调性的最小地层块段搜索法，解决了地层限制、地层尖灭等计算机处理难点。对计算机自动成图领域具有较大借鉴意义。

The Section-map, Column-map is the key and precursor chart during the all geology work and was draw by geologist frequently. The common methods for drawing Section-map and Column-map are handwork. However, the theory and the techniques developing of GIS have spurred the methods changing for automatic way. The thesis designed a data model for drawing Section-map and Column-map automatically, and designed a Drill Data-base based on the many drills data. The programs’ writing uses the Visual C++, adopts the Object-oriented technique. This thesis completed code sum to about 10000 rows, A small CAD system is designed, besides suffice the need of base shape drawing, also including the two modules of automatically drawing of Section-map and Column-map. This CAD system can complete Section-map and Column- map automatically, also it's very easy to add new module because of the applications of the Object Oriented .In this thesis, I create a method of searching the least section to solve the section limitation and section vanish. This method can be used for reference to the area of computer Auto-drawing. Keywords：Section-map, Column-map, Object Oriented Technique, Section Segment Thesis：Application Study
