摘　　要：提出了基于曲面约束的地质层面重构方法,其基本思路是先构建断面形成约束曲面,在地质层面和断层拓扑关系约束条件下,形成基于断层曲面的空间约束的层面插值问题,并在层面穿越约束断面的部分进行矢量裁剪。通过仿真,该方法有效解决了复杂地质构造的层面的矢量重构问题;并通过实际的工区数据测试,有效支撑了复杂地质构造下的构造成图和构造建模应用。由此,该方法回避了现有方法存在的层面区域分割所需边界信息难以获取的问题,并且实现了复杂地质构造的层面矢量重构。This paper proposed the reconstruction algorithm of stratum surface based on constraints of fault surfaces.The basic idea of this algorithm was to build fault surfaces first,forming constraints,then converted the original issue into a matter of surface interpolation and vectorial cutting under fault surface constraints.Through simulation,this method effectively solved the problem of surface vectorial reconstruction under complex geological structure ; and through the test of real field data,this method effectively supported structure mapping and structure modeling.In conclusion,this algorithm evades the problem of getting boundary information which bothers most of the present algorithms,and achieves the goal of surface vectorial reconstruction under complex geological structure.
