摘　　要：针对常规路线断面测量在破碎地形处存在劳动强度大、效率低、数据准确性差的现状,基于Visual LISP语言提出了在破碎地形处构建不规则三角网来自动提取断面数据的一种新方法。实际工程应用表明,该方法能大幅提高断面数据的提取效率,具有一定的生产实用价值。In view of the present situation of high labor intensity,low efficiency and poor data accuracy in the conventional route sectional measurement in the broken terrain,we proposed a new method based on Visual LISP language for constructing irregular triangular network to automatically extract sectional data in the broken terrain.The practical engineering application shows that this method can greatly improve the extraction efficiency of sectional data,and has certain practical value in production.
