Shear Stress Measurements In Situ of Soils Subjected to Vibratory Loads

摘要

A miniaturized shear cell is described. Results of measurements in situ with this shear cell are compared with those of pressure cells.nVibratory (sinusoidal) loads were generated by a mechanical oscillator on the surface of the soil and transmitted to both types of cells buried underneath.nA predominantly homogenous and non-cohesive soil was selected so that as a first approximation the theory for biaxial stress distribution could be applied in the analysis.nThe standard deviations of the corresponding shear and normal stresses did not exceed 5. 3%.
