چکیده مقاله
The major section of the city of Tehran has been developed on cemented coarse grained alluvium In order to understand the mechanical behavior of this soil, a series of undrained cyclic triaxial tests were performed on uncemented and artificially calcite cemented samples In this regard the effects of cement content, confining pressure and cyclic deviatoric stress were studied as well In general by increase in the amount of cementation, maximum shear modulus increases and damping ratio show no significant variation Also, increase in deviatoric strain results in the increase in damping ratio and decrease in shear modulus In addition the higher confining pressures lead to higher shear modulus and lower damping ratio Furthermore the shear modulus decreases with increase in number of cycles
