Influence of Pressure Cone
The pressure cone inclination determines the transmitting of the nail force through the weathered layer. It is considered in the calculation of shear force acting on the mesh. It reduces the horizontal spacing between the nails and the width of the soil block. The reduction result is a trapezoidal shape of a soil block modified to a rectangle shape of width lh,red.
The pressure cone angle θ is entered between 30° and 80°. The pressure cone radius in the upper part rcone is considered as half of the plate length lw.
