摘　　要：目前地质剖面图的绘制算法处理地层缺失、地层尖灭以及透镜体等现象时需要一定的人工干预,且算法智能性较低,无法满足工程需求。针对该问题,提出一种地层连接关系自识别的剖面图绘制算法。首先根据地层分布的特点定义相邻钻孔的地层连接关系,并推导出各非连续分布地层的连接关系的识别方法和连线规则;然后根据地层的岩性和地层连线的平缓确定相邻钻孔中连续分布的地层,对非连续分布的地层进行地层连接关系的识别以及连接处理,从而实现了相邻钻孔地层的自动连接。研究结果表明该算法能够对地层的缺失、尖灭、透镜体等情况做出精确的处理,成图结果与实际情况相符。The current mapping algorithms for geological sections require manual intervention to deal with the phenomena of stratigraphic gap,stratigraphic pinch-out and lens,which has low intelligence and unsatisfying engineering requirements.Considering this issue,this paper proposeed an automatic mapping algorithm of geological sections based on the self-recognition of stratigraphic connection.Firstly,the stratigraphic connection relations of adjacent boreholes according to the characteristics of stratigraphic distribution was defined,and the judgement method and the attachment rule of each discontinuous stratum were deduced.Then,it determined the continuous strata between the two adjacent boreholes based on the lithology of the stratum and the smoothness of the stratigraphic line,recognized the stratigraphic connection relation of discontinuous strata and deal with them accordingly.Thereby the automatic connection of strata in the adjacent boreholes was realized.The result shows that the algorithm could accurately deal with the stratigraphic gap,stratigraphic pinch-out and lens,and the result is consistent with the true circumstances.
