Abstract The shear strength is an important index of mechanical properties regarding to stability and safety of structure. The relationship formula of shear strength of soft clay and shear wave velocity is derived according to the nonlinear constitutive relationship of soil，Mohr-Coulomb strength theory and soil dynamics theory. Comparison of the results of shear strength by field measurement and the relationship formula shows that the relationship formula is effective to calculate shear strength of soil by shear velocity. So a quick，economical and nondestructive testing method for determining shear strength is developed.

Key words： soil mechanics shear strength Mohr-Coulomb strength theory shear wave velocity soft clay
