| Abstract: | The earth retaining wall is a new kind of compound supporting and retaining structure.Taking the double-layer suspended-anchor earth retaining wall as research object,based on the finite element method,the paper studies this kind of retaining wall's design method,and puts forward its calculation method,which is based on Rankine active earth pressure,gives the design demand of wall structure,presents the method of designing anchor plate and drawbar,delivers the stability analysis method toward cantilever retaining wall and polygonal fracture plane stability analysis method.An example results show that this method can be widely used in engineering design.6 figs, 6 refs. |
