Abstract

Fracture persistence is a key parameter for evaluating the geological stability in unexcavated underground sections. It governs potential slurry migration pathways and strongly affects the overall efficiency of grouting. We propose an automated workflow for mapping fracture persistence. First, fracture plane attributes—dip azimuth, dip angle, spatial location, and dispersion—are digitally quantified from borehole data to construct a standardized database. Large-scale fracture occurrences are extracted using these persistence criteria. This provides crucial data on the maximum chord length of the fracture and the corresponding convex polygonal area. Furthermore, intelligent algorithms for persistence judgment and feature extraction are developed, enabling efficient analysis of borehole-induced fractures in tunnels. Numerical simulations spanning diverse borehole and fracture configurations confirm feasibility and demonstrate utility for 3-D visualization and fracture modeling. Additionally, the proposed method has been successfully applied in an oil depot project. This showcases its ability to swiftly and accurately determine the persistence of multiple fracture surfaces. The large-scale fracture information derived from this method offers valuable insights for ensuring the safety of tunnel construction.

基于井眼群图像分析的裂缝持续性创新变换映射与可视化：MFPbia

裂缝持续性是评价地下未开挖段地质稳定性的关键参数。它控制着潜在的浆液迁移路径，强烈影响注浆的整体效率。我们提出了一种自动绘制裂缝持续性的工作流程。首先，从井眼数据中对裂缝平面属性（倾角、倾角、空间位置和分散度）进行数字化量化，构建标准化数据库。使用这些持续性标准提取大规模裂缝发生。这为骨折的最大弦长和相应的凸多边形面积提供了关键数据。此外，还开发了用于持续性判断和特征提取的智能算法，实现了对隧道井眼裂缝的有效分析。跨越不同井眼和裂缝配置的数值模拟证实了三维可视化和裂缝建模的可行性和实用性。该方法已成功应用于某油库工程。这显示了它能够快速准确地确定多个裂缝表面的持久性。该方法获得的大尺度裂缝信息为确保隧道施工安全提供了有价值的见解。
