“…Figure 14 presents the CRRfield-Vs1 correlation results determined for the sand-silt mixture with fc = 15% together with results of previous field and laboratory studies for comparison. The CRRfield-Vs1 correlation data for the sand-silt mixture (D50 = 0.30 mm, Cu = 8.8) of this work lay to the left of the curves recommended by all previous field and most laboratory studies [15,21,23], and practically coincide with those reported by [24] for an artificial sand-silt mixture with fc = 15% and similar grading characteristics (D50 = 0,28 mm, Cu = 9.7) and rounded grains. The maximum estimated Vs1 value is of the order of 144 m/s at Dr = 70%, as compared to the limiting upper value of 204 m/s, proposed in the semiempirical procedure and the upper range of values from 157 to 181 m/s, observed for the results of previous laboratory studies.…”

This paper presents the results of a laboratory investigation into the effect of non-plastic fines on the correlation between liquefaction resistance and the shear wave velocity of sand. For this purpose, undrained stress-controlled cyclic triaxial and bender element tests were performed on clean sand and its mixtures with non-plastic silt. It is shown that the correlation between liquefaction resistance and shear wave velocity depends on fines content and confining effective stress. Based on the test results, correlation curves between field liquefaction resistance and overburden stress corrected shear wave velocity for sand containing various contents of fines are derived. These curves are compared to other previously proposed by field and laboratory studies.

Applicability of soil‐type index for shear wave velocity‐based liquefaction assessment

The current simplified liquefaction assessment method based on the shear‐wave velocity, Vs has uncertainties about how the fine contents change the Vs‐based liquefaction resistance. According to the simplified method, for a given Vs, the cyclic resistance ratio (CRR) increases with an increase in fine contents. However, field investigations recently revealed that for various silty sands, the correlation between CRR and Vs is soil‐type index dependent and not specific for all sand‐silt mixtures with the same fine contents. Therefore, a detailed experimental research program is performed in this study to clarify the effect of the soil‐type index on the shear wave velocity and CRR correlation. In the first part of the present study, the cyclic resistance of sand mixed with non‐plastic (NP) fines (dry weight of 0%, 5%, 15%, and 35%) was investigated using cyclic direct simple shear (CDSS) tests. Seismic cone penetration (SCPT) tests were performed inside the large‐scale box to facilitate normalized cone penetration resistance (qc1N) and shear wave velocity measurements on the soils used in the CDSS tests. A new correlation was proposed between the qc1N and normalized shear wave velocity (Vs1) using the soil‐type index Ic representing the behavior of soil. Then, CRR‐Vs1 correlation was obtained experimentally for four distinct ranges of soil‐type index. Finally, the results of this study and the proposed CRR‐Vs1 trends in other investigations were used to discuss the soil‐type dependent Vs‐based liquefaction susceptibility zones.

The cone penetration test-based simpli ed liquefaction triggering evaluations are largely based on linking liquefaction manifestations in the eld to cone penetration resistance. These relationships are interpreted in such a way that for given penetration resistance, the liquefaction resistance increases as non-plastic nes content (FC) increases. However, several studies have indicated discrepancies in this relationship.Hence, there is a lag in rational scienti c understanding of this observation. In this study, an experimental research program was undertaken to investigate the CPT-based liquefaction assessment by considering the effects of drainage conditions on the relationship between CPT resistance and liquefaction resistance. First, clean sand and silty sands having 5, 15, and 35% FC were tested at different relative densities by stress-controlled cyclic direct simple shear (CDSS) tests to investigate cyclic resistance of silty sand with varying amounts of non-plastic nes. Then, a set of tests involving piezocone penetration (CPTu), seismic CPTu (SCPTu), and direct push permeability (DPPT) were undertaken in a large-scale box lled with the same soils used in the CDSS tests. The large-scale test results quanti ed the effect of drainage conditions (coe cient of consolidation) on cone penetration resistance. Finally, by combining the CDSS and CPTu test results, an alternative CPT-based liquefaction resistance relationship was proposed by considering the effects of drainage conditions.
