Study on stress distribution and extrusion load threshold of compressed filled rock joints

Applied Rheology, 2023
The distribution of stress and the normal extrusion load threshold in weak interlayer are crucial for direct shear test of filled rock joints, but there is a lack of theoretical research in this area. First, an analytical solution for stress distribution
