Test application:
Used to determine the dynamic shear strength deformation and shear modulus of coarse grain soil, usually using a test piece under different vertical pressure, apply shear force to shear, to obtain shear stress when damaged;
Determine the shear strength coefficient, internal friction angle and cohesion according to Cullen's law. According to the required set of dynamic shear stress frequency, waveform, obtain the dynamic shear deformation calculate the shear modulus for analysis and evaluation.
The shear strength (or anti-liquefaction strength) characteristic test should use the fixed non-drainage vibration test conditions, the constant shear stress deformation characteristic test should use the fixed non-drainage vibration test conditions.
Trimming residual deformation characteristics test should use fixed drainage vibration test conditions.
The purpose of this experiment is to determine the destructive strength of saturated soil under the action of kinetic stress (including liquefaction) and to calculate the kinetic characteristics of elastic modulus of shear for analysis.
