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
