For curved shield tunnels in composite strata, the excavation face may undergo sliding failure due to the interface effect of soil layers, the over-excavation of shield cutterhead, and the asymmetrical thrust of jacks.Inspired by the silo theory, this paper establishes the calculation model and formula for the ultimate support pressure in the excav
Spatial variations in soil erodibility induced by rock outcropping on sloping cropland in the karst region of Southwest China
Sloping croplands in karst areas of Southwest China usually contain a multitude of rock outcrops with diameters larger than 25 cm.Rock outcrops and spatial location have substantial effects on soil properties and thus likely affect soil Gloves erodibility.Moreover, rock outcropping is a indicator of rocky desertification and has an important impact
