Abstract Soil-rock mixture(S-RM) is a kind of inhomogeneous geometrical，compared with rock mass or soil，it has variability of material composition，and more complicated space structure，up to now the experimental study of its mechanical parameters are lack of mature theory and technology. Taking a large soil-rock mixture in Liyuan hydropower project area as an example and on the basis of a large in-situ experiments，its characteristics of strength and mechanics are discussed，physico-mechanical parameters are determined by engineering geological are analyzed as well. Researched results show that it has complete shear stress to shear displacement curve and high shear strength in the natural state，it is not only to lay a foundation for stability analysis of soil-rock mixture，but also to provide relevant experience for similar project construction.

Key words： engineering geology large soil-rock mixture engineering geological characteristics in-situ test physico-mechanical properties characteristics of strength
