Due to new tectonics movements and drastic climate change
there are different types
and thicknesses of sediment on Quaternary soft clay in Hangzhou region
which have some characteristics of structural properties in particular. In order to investigate the dynamic characteristics of Quaternary soft clay in Hangzhou region
a series of dynamic triaxial tests are conducted. The stress-strain backbone curves and some kinds of dynamic property parameters of structured soft clay in Hangzhou are obtained. It is discovered that the change of the sediment environment is a cause to structural properties of soft clay in Hangzhou region and affects initial dynamic elastic modulus Ed0 obviously. On the side of the maximum amplitude on dynamic strain
the control of structural properties of soft clay is random and unobvious. Generally
there is a good power function relationship between the shear wave velocity and buried depth of structural soft clay
but the different kinds of structural soft clays may have different relationships. In addition
it is shown that structural properties of soft clay could have some influences on the relationship between damping ratio and shear modulus.
