THE CORRELATION STUDY OF LOESS STRUCTURAL AND SHEAR STRENGTH

At present, there is not a systematic study for the relationship between the structure and shear strength. The author conducted consolidated drained triaxial shear tests for the slope loess of Jinnan, to study the correlation regular of the structural parameters and shear strength. The results show that under the combined effect of strength and water, when the pressure is small and water content is low, the structure is stronger, and the structure becomes weaker with the increasing of pressure and water content. When the structural is big, then the shear strength is also big.
