RESEACH ON SATURATION EFFECTIVE SHEAR STRENGTH PARAMETERS OF JINGYANG LOESS

Saturation effective shear strength parameters(c',') are the basic parameters for the establishment of unsaturated soil shear strength. In order to investigate the relation between c ',' and the depositional age of loess, intact samples from L1,S1,L5 and L9,were taken from Jingyang, Shanxi Province. Using consolidated undrained(CU)test of conventional triaxial apparatus, obtain the effective shear strength parameters c' and '.Established the empirical estimation model between c' of Jingyang loess and the depositional age.
