摘　　要：三维地质建模对工程决策、地质分析预测及提高制图效率有非常重要的意义。通过一个工程实例,详细地阐述了三维地质模型的建立过程,包括数据的分析和预处理、表面和实体的生成、断层和地层以及三维地质模型的其他要素的处理。最后,利用GemCom软件平台生成一个适用于实际工程的三维地质模型,并对其进行了检验。另外,提出了使用拉普拉斯插值法和不规则三角网结合的三维表面生成方法,相对于传统的不规则三角网有很大改进。Three-dimensional geological modeling is important for engineering decision,geological analyses and prediction,and improvement of cartographical efficiency. Through an engineering example,the process of establishing a three-dimensional geological model,including data analysis and pretreatment,surface and solid creation,the disposal of the fault,stratum and other factor concerned with the three-dimensional geological modeling,is elaborated. A three-dimensional model suited for engineering project is produced by using GemCom software platform and is examined at last. In addition,the method of adopting Laplace interpolation integrated with the irregular triangle net (TIN) to create a three-dimensional surface,which has much more progress compared with the traditional irregular triangle net,is put forward.
