摘要在运用平面地质图数据、露头数据和钻孔数据进行复杂地质体三维地质界面重构的过程中，详细分析三维地质界面重构中的几个核心问题，包括：界面确定、三维插值、几何造型和合理性评价。在此基础之上提出基于地质成因分析的地质界面重构方法，此方法可以更好地整合复杂多样的地质数据，更合理有效地确定复杂的地质界面，并且使三维地质界面重构和三维地质建模更加的智能化，即减少人为的干预。最后用一个工程应用实例对此进行展示和验证。

Abstract：Data from geological map，outcrop and borehole were utilized for the reconstruction of geological surfaces of complex 3D geological body. Detailed analysis of core issues in 3D reconstruction of geological interfaces was conducted including the interfaces determination，3D interpolation，geometric modeling and evaluation of reasonableness. A method of geological interfaces reconstruction was proposed based on the evaluation of geological cause of formation. This method integrated the complex and diverse geological data better and determined the complex geological interfaces more rationally and efficiently. Therefore，the method made 3D reconstruction of the geological interface more intelligently as a result of reduction of human intervention，which was verified and demonstrated in an example of engineering application.

Key words： engineering geology geological interface fault interpolation surface fitting 3D reconstruction 3D geological modeling
