| Abstract: | The dynamic shear modulus and damping ratio of soil are two principle parameters of soil dynamic characteristics.They are the foundational data in designing ground motion parameter for important project＇s site.Combined with the seismic safety evaluation work of Xinbei Oil Field Project,Using DDS-70 dynamic triaxial test system produced by the Institute of Beijing New Technology,we carried out dynamic modulus and damping ratio study on muddy clay,silty clay,silt and sand soil.The experimental result was compared to other relevant study result.The accumulated basic data and method of this study can provide reference for the seismic safety evaluation of the related marine construction projects close to the study area. |
