摘　　要：针对航道地质剖面图自动生成算法存在不能自动生成断层、褶皱等地质构造和局部微调整不全的问题,文章研究了航道地质剖面自动成图的算法,提出了一种基于点、线、面、链、链组的五级矢量数据模型及对应的拓扑结构,对地质剖面自动生成和屏幕热调整进行了设计与实现,为航道疏浚工程管理提供了有力的决策依据。In view of the problems that the current automatic generation algorithm of channel geological profile can not automatically generate faults,folds and other geological structures and local micro adjustment is incomplete,this paper studies the automatic generation algorithm of channel geological profile,and puts forward a five-level vector data model and corresponding topology based on point,line,surface,chain and chain group.The principle of automatic generation of geological profile and screen thermal adjustment is designed and realized,which provides a powerful auxiliary decision-making basis for channel dredging project management.
