Abstract
Starting from the action mechanism of geogrid reinforced cushion and according to Terzaghi theory,the author introduces two methods to calculate bearing capacity of geogrid reinforced cushion,proposes computing formula of vertical stress under reinforced cushion influenced by anisotropy characteristic of geogrid cushion,thickness of cushion and angle of spread,and puts forward the method to design the thickness of geogrid cushion according to Japanese experiences.
