dynamic properties of calcareous sand from the persian gulf in comparison with siliceous sands database

Results of several cyclic triaxial and resonant column experiments on calcareous sand were presented by the authors in a preceding paper to obtain the shear modulus and damping ratio of the sand under various effective confining pressures and relative densities. the calcareous sand was taken from bushehr, one of the most strategic ports of iran in the persian gulf. this technical note compares dynamic properties of this coastal sand with a comprehensive database compiled from the experiments on various siliceous sands. the discrepancy observed between the experimental results of the calcareous sand and those of the siliceous sands is demonstrated. these differences can be attributed to the grains’ shape, mineralogy, and texture of the calcareous and siliceous sands. the comparative study provides useful insights into the dynamic properties of the studied calcareous sand.
