摘要：Aimed at researching intact loess mechanical properties in Qinghai area, this paper analyses these parameters through consolidated and undrained triaxial tests and SEM tests, and tests results are fitted linearly. The results show the maximum deviatoric stress increases with the increase of confining pressure when loess moisture contents are same. SEM images of loess clearly illustrate the close relative between moisture content and the pore distribution. The relationship between water content and shear strength index c and and ratio of pore area is nearly linear. Through using moisture content parameters, loess strength and pore ratio can be deduced by fitting linearly formulation, which has certain reference significance to the local engineering construction.
