Abstract: For complex fault network, a new path cut algorithm was proposed, by which all types of complicated fault intersection can be dealt with, such as Y, λ, X, half-Y, half-λ contact relations. This fault modeling method not only avoids the limitation of the Pillar method and binary tree method, but also greatly improves the flexibility and accuracy of fault modeling. The method improves semi-automatic processing of the contact relationship between faults and quick updating of fault models. Through the validation of practical model, the modeling of complex fault network can be successfully and quickly solved, and the efficiency of modeling was also greatly improved.

Key words: fault networks, contact relationship, path-cut algorithm, binary tree, Pillar method

摘要： 针对复杂断层网, 提出一种新的路径切割算法, 能够处理各种复杂的断层相交情况, 如Y型、λ型、X型、半Y型、半λ型等削截关系; 避免了Pillar方法和二叉树等传统方法的限制, 提高了断层建模的灵活性和精确度。该方法提高了断面之间接触关系的半自动处理程度, 方便断层网的快速更新。通过实际模型的验证, 解决了复杂断层网的快速构建问题, 提高了建模效率。
