查询词典 test paper

Through contrasting and analysing the experimental results from these methods, the paper summarizes the regularity of collapsing deformation and the shear strength index changes with the degree of saturation and stress, describes the collapsing deformation properties and strength characters of the collapsible loess in the course of moistening and drying, and describes the influence to collapsing deformation of loess from different paths of stress. Through performing monaxial compression test on samples with different paths of inundation and direction of press, proves the conclusion that collapse has nothing to do with the path of inundation and the collapsible loess has the prominent anisotropy characters.
