数字地质填图数据构建断层面的方法

Technological methods of build Fault plane based on digital geological mapping data

为准确构建浅地表复杂断层面,采用"地表填图数据为主,地下断层数据为约束"的方法.研究结果表明:该方法构建的断层面与地表断层数据和地下断层数据能够完全吻合,受地表产状可推测深度的限制,该方法仅适用于浅部断层面的构建.断层面的精度取决于地表填图数据的数量和精度,在断层产状变化大的部分需要适当增加产状数据.

The construction of 3D geological model is mainly to build geological interfaces, in aiding to accurately build complex fault plane, adopting the way of ＂field line data as the main data, subsurface geological data as the constrained data＂ to build shallow fault surface. It proves that the fault plane built by this method can be matched with the surface fault data and sub-surface fault data. Due to the limitation of depth of surface attitude, this method is only applicable to build the shallow fault surface. The accuracy of fault plane depend on the quality and quantity of the data in the process of surface mapping, and at the location of the geological boundary large changing needs to increase the data of attitude.
