A Study the Tensile Failure of Reinforced Earth Retaining Wall with Model Test

According to the reinforcing mechanism and the earth tensile crack,the location and shape of cracking surface behind the reinfored earth retaining wall are reasonably assumed.Starting from the integral strength charac-teristic of reinforced earth,this paper prasent:a formula of critical reinforcing ratio for the tensile failure of rein-forced earth retaining wall.The results of theoretical analysis and model test are in good correspondence with eachother.
