Four tests were conducted under various vertical stresses: 100, 200, 300, and 400 kPa. The vertical pressure can be gradually applied or in steps to prevent sample extrusion, especially if the soil is loose. Let us rotate the handwheel until the steel ball at the front end of the upper ...
remains rudimentary, with singular processing methods that fail to fully extract geological insights. To address this, this study introduces a method for processing aerial survey image data of high-risk rock masses on high slopes, utilizing unmanned aerial vehicle point clouds. The steps are as ...
LiDAR-derived data were analyzed in three steps. First, elevations from the LiDAR DEM were compared to field-surveyed elevations collected along the road centerline. DEM elevations were extracted for the exact location of the 126 field-surveyed checkpoints. The differences in elevation between the ...
The length L3 of the rubble in contact can be calculated using Equation (2): L3 = L2 − L1, (2) where L1 is the strike length from the lateral fracture line to the end of the immediate roof in meters. Because rock beam A makes sufficient contact with the rubble inside the gob, ...
