摘要:
针对现有网格模型大多存在失真和变形等问题，提出一种基于离散光滑插值（discrete smooth interpolation，DSI）方法的三维地质体构造网格模型.通过数字化依次建立地质空间和参数空间的换算关系，使当前地质空间的任何点在参数空间中被重新定位，解决了基于地质体构造网格模型解决纯六面体地质网格的建模难题.利用某水电站工程实际测量和地质钻孔等数据进行验证，结果表明，该方法能有效满足实际工程的三维地质建模和岩土数值分析需要.
Abstract:
In view of the distortion and deformation problems in the existing grid models, this paper proposes a 3D geological grid model based on the discrete smooth interpolation (DSI) method. The proposed method establishes the conversion relationship between geological space and parameter space through digitization, so that any point in the current geological space can be repositioned in parameter space. Using the proposed method, pure hexahedral mesh can be achieved by a 3D geological grid model. The proposed method is verified by the actual data of a hydropower station project. Experimental results indicate that the proposed method can effectively meet the needs of actual 3D geological modeling and geotechnical numerical analysis.
