By the soil mechanical method,grounded on the results of triaxial compression tests,a quantitative parameter of structural properties,which can reflect structural property of the disturbed loess and saturated intact loess,has been proposed.Then,a study of structural properties of disturbed loess,saturated intact loess has been carried out primarily.A large number of routine triaxial tests are carried out on the unsaturated soil triaxial apparatus for different water content of disturbed loess,saturated intact loess and saturated disturbed loess.The variation regularity of disturbed loess and saturated intact loess has been studied minutely,and the applicability of the new structural parameter has been confirmed.These works will improve the quantitative parameter of structural properties of loess.
