Abstract


Karamay Xinjiang ( northern ) regions S201 line to Yushugou section of highway along the saline soil as the research object , through the indoor routine testing more systematic study of the physical and mechanical properties . In saline soil collapsibility behavior under uniaxial compression test with a single , two-line method ; in saline soil shear strength test , respectively, with the triaxial and direct shear two test methods. Comparison and analysis on the test results , summed up the saline soil dissolved collapse deformation and shear strength and water content , salt content and stress changes in the law , and dissolved saline soil in these conditions change collapse deformation characteristics of traits . Finally, we discuss the impact of the freeze-thaw cycle different soil saline soil moisture migration and density and shear strength . Trial found that repeated freezing and thawing strongly affect the mechanical properties of the saline soil , especially the top of soil than the silt and clay by large .
