The correlation between blow counts of dynamic penetration tests and shear wave velocities is researched by analyzing abundant numerical statement in cobble soils. The regression equations of quadratic polynomial
exponential function and power function are derived
of which the exponential function regression equation is more suitable for the correlation. The feasibility of the exponential regression model is verified by the results of surface wave testing and dynamic penetration testing in a similar site. It is shown that the surface wave velocity method can be used to not only determine the ground conditions
but also quantitatively evaluate its bearing capacity.
