Abstract:

The strength characteristics of unsaturated red clay is an important calculated parameter of foundation engineering,slope engineering and underground engineering. The strength characteristics of Guiyang unsaturated red clay are studied by the triaxial test.The stress-strain relation and breakage type for original red clay and compacted red clay are discussed.The mathematical model of stress-strain relation for compacted red clay is presented. The relation between shearing intensity parameters and physical properties is obtained.

Key words: unsaturated red clay, general triaxial test, stress-strain relation, shearing intensity parameters
