Abstract

The characterization of discontinuous rock mass properties is essential for understanding the behaviour of rock masses in various engineering applications, such as tunnelling, mining, and slope stability analysis. This study presents an innovative approach for detecting and extracting the orientations of discontinuous rock plane replicas using image analysis techniques. The image analysis technique employed in this research involves the use of advanced algorithms in Agisoft Metashape to process digital dense point clouds, enabling the identification of discontinuities and the extraction of dip and dip direction in CloudCompare software. The performance of the image analysis technique was evaluated using the Root Mean Square Error (RMSE) for dip and dip direction measurements. The RMSE values were 1.97 for dip and 2.34 for dip direction, indicating high accuracy and reliability in-plane detection. Additionally, the range of differences observed was within 5 degrees for dip and within 13 degrees for dip direction. These results support the interpretation of RMSE, highlighting the sensitivity of dip direction in image analysis.

期刊介绍： The aim of the Journal is to publish research results of the highest quality and of lasting importance on the subject of geomechanics, with the focus on applications to geological energy production and storage, and the interaction of soils and rocks with the natural and engineered environment. Special attention is given to concepts and developments of new energy geotechnologies that comprise intrinsic mechanisms protecting the environment against a potential engineering induced damage, hence warranting sustainable usage of energy resources. The scope of the journal is broad, including fundamental concepts in geomechanics and mechanics of porous media, the experiments and analysis of novel phenomena and applications. Of special interest are issues resulting from coupling of particular physics, chemistry and biology of external forcings, as well as of pore fluid/gas and minerals to the solid mechanics of the medium skeleton and pore fluid mechanics. The multi-scale and inter-scale interactions between the phenomena and the behavior representations are also of particular interest. Contributions to general theoretical approach to these issues, but of potential reference to geomechanics in its context of energy and the environment are also most welcome.
