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 problem of uncertainty in 3D geological modeling has a direct impact on model accuracy, spatial data analysis and application effects. By analyzing the uncertainties existing in all aspects of 3D geological simulation, a three-dimensional geological simulation process based on uncertainty was established and an effective method of error detection and analysis and correction was proposed. Taking the complex geological structural fault modeling in the mining area as an example, the problems of logical inconsistency, data incompleteness and tectonic feature deduction are studied, and the error and evaluation of the fault model are analyzed. Experiments show that the proposed method can reduce the spread of uncertainty and improve the accuracy and quality of the model.
