- Abstract
The shear-wave velocity of rock and soil masses is the quantitative basis for understanding the dynamic parameters of site soil and evaluating its dynamic performance. The field test and laboratory test are two major methods and it is necessary to study the difference of the test results obtained by the two methods, especially for conventional soils like silt and silty clay. This study selected two typical sites to conduct field test and laboratory tests of shear-wave velocity and measured the shear-wave velocities of the obtained undisturbed soil samples of silt and silty clay in the laboratory. The results suggest that: (1) almost all shear-wave velocities of silt and silty clay obtained in laboratory test were faster than those in field test; (2) the main reason causing the difference between the two methods was that soil samples lost water during the acquisition and transportation, resulting in declining soil moisture; and (3) factors including structural change of soil samples, existence of soft and hard interlayers, and testing environmental in the field also contributed to the difference of the test results of shear-wave velocity.
