Comparison of methods for evaluating of slope stability on high embankment built with the use of bottom ash

Abstract

The article discusses the possibility of using the software complexes, which laid the basis for the finite element method (ZSoil, Plaxis, GEO5 FEM), to evaluate the stability of the sloping parts of embankments roads built with the use of bottom ash. The paper presents the results of numerical simulation and assessment of the stability of the sloping part of the road embankment on the 1B category highway with a height of 15 m built with the use of bottom ash from Kashira's TPP-4.In conclusion, it was a comparison with the results of assessment of the overall sustainability of the same constructions for widely used in the practice of construction techniques limit equilibri-um (Bishop, Fellenius, Shahunyants).
