报告摘要：

Digital technologies have great potential to improve capabilities and efficiency in geotechnical work. Geologists often spend considerable time logging rock cores and creating investigation records, which are vital for engineering practices. A project at the University of Hong Kong (HKU) is leveraging advances in AI and mobile devices to develop a web-based application that aids rock core logging, potentially transforming geotechnical practice. This seminar will focus on creating a computational algorithm that automatically determines the fracture index (FI) of core runs using fracture spacing data. The primary evaluation indicator is the variance of fracture spacing values. The algorithm automatically groups fractures seen in core images, considering the uniformity of fracture spacing when calculating the FI. The anticipated research outcomes aim to enhance routine core logging practices, which are presently performed manually and prone to human errors.
