Analysis of Shear strength of High Slope Clay with different Water saturation
In this paper,the consolidated undrained tests of the remolded clay samples of a high slope under different water con-tent were performed under different consolidation pressures(50,100,200 and 400 kPa).The results show that the water con-tent has a significant influence on the shear strength of the remolded clay.The lower vertical pressure will make the pore water pressure in the sample dissipate incompletely in the short-term consolidation process,resulting in a lower effective stress,re-sulting in obvious hardening or softening.When the degree of saturation is more than 80.23％,the cohesion of the sample de-creases obviously.In addition,combined with nuclear magnetic resonance analyzer,the pore water distribution in soil samples with different degrees of saturation is analyzed.It is proved that the water in the small pores will flow into macropores under external load,which provides evidence for the sudden decrease of cohesion in the direct shear test.
