APPLICATION OF JANBU LAW TO STABILITY ANALYSIS OF REINFORCED EMBANKMENT OVER THIN SOFT FOUNDATION SOILS

This paper studies the overall stability analysis method of the establishment of the corresponding reinforced embankment on the basis of Janbu Law, in light of the characteristics of thin soft foundation. Under certain assumed conditions, thin layer of soft foundation safety coefficient expression and the tangential force of expression are deduced in accordance with the principle of reinforced cushion action principle and through the stress analysis of reinforced material and the overall stability of the embankment limit equilibrium analysis of reinforced cushion. The overall stability and safety factor of reinforced embankment cushion based on Janbu Law are obtained through iteration. Then, Python language is adopted to program the overall stability evaluation method of reinforced embankment proposed in this paper. Combined with the calculation and analysis of practical cases, the feasibility of the established stability analysis method is verified.
