THE SHALLOW FORMATION WAVE SPEED DETECTED BY STEADY-STATE RAYLEIGH WAVE METHOD

the shear wave speed is the most suitable index for the site foundation classification.The Rayleigh wave speed is very close to the shear wave speed.By the simple comparison of several methods,the principle,characters and problems using the Rayleigh wave method to detect the formation wave speed are introduced.The practical application indicates that this method is better than other ones for the determination of shallow formation wave speed.
