Orthogonality Analysis Method of Sensibility on Factor of Sand Embankment Slope Stability

Abstract:

In order to clear the slope geometry, surrounding soil parameters, sand filling parameter and other factors on the degree of influence of sand embankment slope stability, the sensitivity of the sand embankment slope stability influences factors was analyzed by using the orthogonality analysis method. The results show that the sequence of these influencing factors in terms of the influencing degree on the slope stability is embankment height > the friction angle of sand > the friction angle of surrounding soil > the cohesive strength of surrounding soil > slope gradient > the cohesive strength of sand > the bulk density of surrounding soil > thickness of surrounding soil > top layer thickness > the bulk density of sand. The embankment height, the friction angle of sand and the friction angle of surrounding soil are highly significant factors. The cohesive strength of surrounding soil, slope gradient and the cohesive strength of sand are significant factors.
