摘　　要：为利用钻孔数据快速构建三维地质模型并进一步提高模型合理性和数据质量,提出了基于钻孔的三维地质模型快速构建及更新方法。利用基于层位标定的钻孔数据快速解译方法完成原始钻孔中地层分界点的编号之后,实现了三维模型的自动构建;通过在约束条件下调整层面虚拟控制点,完成了模型的交互式调整,并能根据调整结果自动更新三维模型。该方法在建模实际案例中的成功应用,证明其能够很好地处理工程实践中的复杂问题,提高了建模效率及模型质量。In order to quickly construct 3D geological models from boreholes as well as to enhance the model rationality and quality, the quick construction and update method of 3D geological models based on boreholes is presented. After the numbering of contacts in boreholes, during which the quick borehole data deciphering method based on stratum tagging is used, 3D models can then be built automatically. The interactive adjustment of models is achieved by means of changing virtual contacts with con- strains. Models are then automatically updated according to the adjustment. The successful application of the presented method to practical modeling of some area demonstrates that the method is able to address complicate problems. It also accelerates the modeling process while ensuring the correctness of the models.
