In the past three-dimensional geological modeling process, only vertical geological data, i.e. borehole or profile drawn from borehole, was used as the modeling data source. However, the plane geological map either does not participate in the modeling at all, or only serves as a reference data in the modeling process, and its role is not fully played. In view of the appeal, this paper puts forward a plane section modeling method based on multiple constraints. This method combines the vertical geological data and the horizontal geological data to participate in the modeling work. The surface part of the 3D geological model constructed by this modeling method is completely consistent with the plane geological map. In addition, there are both vertical data source and horizontal data source, which greatly improves the accuracy of the model. In this paper, taking the kangyangju area of Huaying Mountain in Guang’an City as an example, using the plane section modeling method with multiple constraints, the three-dimensional geological model construction of kangyangju area is carried out, which proves that the method is reliable and useful, and is worth popularizing.
