HIGH REINFORCED SOLPE AND RELATED COMPUTATION METHOD

Use of reinforced soil technology is of great significance for Western China to reduce the land occupation of high embankment.With the increase of the fill height,the strength and extensibility of the reinforcement,as well as the analysis method is facing challenges.In this paper,the author studied the principle of stability analysis of reinforced slope,discussed the advantages and disadvantages of different approaches to simulating the effect of reinforcement by finite element method(FEM),focusing on the equivalent additional stress method and its improvement.The author put forward the calculation method of strain ratio coefficient,which makes the method being still feasible in the case of incompatible deformation occurs between reinforcement and soil.In addition,the author discussed other key issues involved in the high reinforced slope.
