摘要

Collecting the borehole records of nearly 40 ocean-platforms in Bohai Sea and combining indoor dynamic triaxial test, the authors sorted out 372 original data tested by undisturbed soil sample dynamics of the Bohai Sea. By use of the mathematical statistics method, the authors obtained the average curves and statistical values of dynamic shear modulus and the damping ratios, both of them varied with the shear strain in different soil types and different depth in Bohai Sea. The results could be used as a supplement to the soil dynamics study, was helpful of deepening the understanding about dynamic property of different soil, and provided experience and reference for the seismic safety evaluation of other engineering construction projects in Bohai Sea.
