摘　　要：水利管线工程一般具有长度长、范围小、穿越地形多样、地质条件要求相对简单且设计方案多变等特点。传统的基于纸质地图的地质测绘方法在管线工程地质测绘中存在现场视野狭窄、定点较慢、效率较低等缺点。数字化填图技术的出现使得地质测绘工作的效率大幅提高,已成为当前外业工作发展的一个重要方向。但开发专用的数字化填图软件存在周期长、费用高、兼容性差等不利因素。利用现有的地图软件则可在规避诸多不利因素的同时,保证质量、提高效率、节约成本。以百色水库灌区输水管道为例,介绍了现场数字化填图的方法及成果。The water pipeline engineering is generally characterized by long length, small scope, running through ar- ea with variable terrain and relatively simple geological conditions, multiple design schemes. The traditional geological mapping method based on paper maps has the shortcomings such as narrow field of view, slower fixed-point and low efficiency. Digital mapping technique is able to greatly improve the efficiency of geological mapping, and has become the development direction of field work. However, the development of special digital mapping software has the disadvantages of long period, high cost and poor compatibility. Utilization of existing map software can avoid many disadvantages while ensuring quality, improving efficiency and saving cost. Taking the water pipeline work of Boise Reservoir Irrigation Zone as example, an introduction was mapping. made on the method and achievements of field digital
