摘　　要：针对底辟构造、褶皱等复杂地质体的三维描述与模拟,一直是三维地质建模领域面临的挑战,而且至今仍缺乏完善且易于操作的系统实现,在对复杂地质体的建模方法研究的基础上,采用插值拟合的地质曲面生成的方法,利用三角网格模型结合离散光滑插值(DSI)方法进行多值曲面的生成,实现了多值曲面类蘑菇体的建模。3D modeling of complicated geological entities such as diapirs and folds is a challenge to the research field of 3D geological modeling, which still lacks any perfect and promising system implementation now. Based on the modeling research of complicated geological entities, adopt the method of interpolating and approaching geological surface, use triangular mesh combined with DSI method to generate the multi-surface. This method is applied in the mushroom-like shape modeling.
