Abstract
AbstractTriaxial shear experimental research is conducted on intact unsaturated aeolian soil, remolded unsaturated aeolian soil, and intact saturated aeolian soil under three different dry densities and seven different moisture contents using the true triaxial apparatus TSW-40. Moreover, the relationship between structural parameters and structural strength indexes of intact unsaturated aeolian soil is explored. Test results show a negative correlation between structural parameter ratio mϵ/mϵ0 and moisture content w but a linear positive correlation between structural parameter ratio mϵ/mϵ0 and dry density ρd. The functional relationships between the ratio of structural strength indexes tanϕ/tanϕ0 and c/c0 and structural parameter ratio mϵ/mϵ0 are all a quadratic function. The quantitative index or value of synthetic structural state Pcs, which reflects the effect of different factors on the structural characteristics of intact unsaturated aeolian soil synthetically, is constructed. This paper considers t...
