英文摘要: Abstract(#br)Herbaceous vegetation is an important factor for control of shallow slope failure. While roots of herbaceous vegetation rarely cross potential shear planes, they increase soil cohesion in the top soil and create a surface-mat effect. The surface-mat is a dense layer of laterally interwoven plant fibers, which create considerable horizontal tensile strength of the top soil. Through redistributing impacting forces from unstable towards stable slope areas, the surface-mat can prevent shallow slope failure.(#br)We present a method for measuring the horizontal tensile strength of the top soil, which estimates the surface-mat effect. On four montane grassland slopes in Northern Italy, grass sods were cut out from the soil and their tensile strength was measured with a traction...
