Appraisal Research on Rayleigh Wave Method for Gravel Piles Composition Foundation

摘要

Rayleigh wave method is a relative new in-situ method to the evaluation of low-amplitude shear wave velocity V_s in soil as a function of depth. The method is investigated to appraise the treatment effects of gravel piles anti-liquefaction. The appraisal results of the shear wave velocities measured by Rayleigh wave method are consistent with SPT's. The relative formula of shear wave velocities with N_63.5 is presented based on the regression analysis. Rayleigh wave method is applied to determine the shear wave velocity of soils in a simple, nondestructive way.
