The empirical correlation between shear wave velocity and penetration resistance for the eolian sand deposits in the city of Olmos-Peru

Abstract

Shear wave velocities (Vs) and the number of blows of SPT (N) are parameters that are generally recorded in a geotechnical exploration campaign, in the literature there are several publications on the empirical correlations between N y Vs in different types of soil, the first studies being attributed to Japanese researchers in the 60s and 70s. North Peruvian pipeline was built on a recent quaternary eolian deposit, so a research area in Olmos near to the structure was used for tests. In the geotechnical research campaign were carried out in an arrangement multi-channel and standard penetration test in order to obtain Vs and N respectively. The correlations in this publication are for eolian sand deposits that can potentially be used in other regions with similar characteristics. The correlations presented are; N₆₀ - Vs considering and incorporating into the model the influence of the effective overload.
