Experimental Research on the Characteristics of Soil Strength Freeze-Thaw Weakening in Songhua River Songpu Bank
In order to study characteristics of soil strength freeze-thaw weakening in the Songhua River Songpu bank, basic physical parameters tests and triaxial compression tests were performed on that paragraph bank. The results showed that: after thawing the sample cohesion will drop substantially, the internal friction angle will increase greatly and soil shear strength will increase significantly; the cohesion of sample after repeated freezing and thawing will significantly decline, internal friction angle of soil will greatly increase, the soil shear strength will increase after the first freezing and thawing, with the increase in the number of freeze-thaw cycles, the soil shear strength will significantly decline. The results can provide Songhua slope stability analysis with a scientific basis.
