摘要
三维地质模拟中的不确定性问题直接影响模型精度、空间数据分析和应用效果。通过分析三维地质模拟各个环节中存在的不确定性问题,建立了基于不确定性的三维地质模拟流程,并提出误差检测与分析校正的有效方法。以矿区复杂的地质构造断层建模为例,研究了逻辑不一致性、数据不完整性以及构造特征推演等问题,并对断层模型误差与评价进行了初步分析。实验证明,所提出的方法能够减少不确定性的传播,提高模型的精度和质量。
The uncertain question of 3D geology modeling straight influences the precision of models,spatial data analysis and application effect.Based on the development of uncertain existing on 3D geology modeling,a framework of 3D geology modeling with uncertainty was put forward.An effective method about error checking and revision was researched.And then,the theory was applied to a concrete example of complex fault simulation on a mine area to avoid the logical conflict,insure the data integrality,and extrapolate the structure feature.The error of fault models and its estimate could be also implemented.The experimental results show that the methods designed can reduce the spread of uncertainty and improve the precision and quality of 3D models.
