The geometry of joints has a significant influence on the mechanical properties rocks. To simplify curved joint shapes in rocks, shape is usually treated as straight lines or planes most laboratory experiments and numerical simulations. In this study, computerized tomography (CT) scanning photogrammetry were employed to obtain internal surface structures limestone sample, respectively. describe geometry, edge detection algorithms three-dimensional (3D) matrix mapping method applied...
Abstract The interaction between concrete structures and rock foundations is a crucial research topic for assessing safety stability in geotechnical underground engineering. uniaxial compression tests were conducted on different combination modes (concrete component heights ( H c ), interface inclination angle β coarse aggregate contents) to investigate their impact the mechanical energy response of concrete–granite composite specimens (CGCSs). This study categorized three failure modes:...
<title>Abstract</title> The abrasive water jet (AWJ) is an innovative technology employed in underground engineering to enhance the stability of surrounding rock, facilitate unconventional oil and gas development, rock breaking tunnel engineering. However, current AWJ cutting systems often face challenges related intricate operational processes incontiguous supply particles. Here, a novel slurry (S-AWJ) system has been developed fulfill requirement Some rock-cutting experiments under...
