Research on Experiment of Unsaturated Soil's Shear Strength of Yellow River

With the special unsaturated soil triaxial apparatus to test the sh ear strength,then get the unsaturated soil curves under different moisture cont ents and the shear strength envelopes.According to the relationship of moisture content and total cohesion,we compare the unsaturated soil shear strength under different moisture contents,and imitate the function to get the unsaturated soil shear strength formula.
