“…14. The more recent relationship established by Ahmadi & Paydar (2014) from two types of clean sands, namely the Firoozkooh and the Babolsar sands, are also shown in Fig. 14, and the one based on the Babolsar sand gives much less satisfactory evaluation than that of the Firoozkooh sand.…”

“…This is especially true for sites underlain by soils that are difficult to penetrate or sample (Andrus & Stokoe, 2000;Kayen et al, 2013). The V s -based simplified method has attracted an increasing number of studies, and various 'boundary curves' have been relatively well established on the basis of either field data (Robertson et al, 1992;Andrus & Stokoe, 2000;Juang et al, 2001;Andrus et al, 2004;Juang et al, 2005;Kayen et al, 2013), or laboratory studies (Dobry et al, 1981;de Alba et al, 1984;Tokimatsu & Uchida, 1990;Chen et al, 2005;Wang et al, 2006;Zhou & Chen, 2007;Baxter et al, 2008;Zhou et al, 2010;Ahmadi & Paydar, 2014).…”

“…20). One possible explanation for these observations is that V s -based correlations are soil specific; however, establishing individual relations would be rather costly and time consuming (Tokimatsu & Uchida, 1990;Zhou & Chen, 2007;Baxter et al, 2008;Zhou et al, 2010;Ahmadi & Paydar, 2014).…”

The liquefaction resistance in a soil deposit, commonly quantified by the cyclic resistance ratio (CRR), also depends on its current state (Seed & Idriss, 1971;Tokimatsu & Uchida, 1990;Chen et al, 2005;Wang et al, 2006;Baxter et al, 2008;Ahmadi & Paydar, 2014). CRR is generally estimated by performing cyclic triaxial tests on reconstituted samples following a given stress path (e.g.…”

The shear wave velocity method has become an increasingly popular means to evaluate the liquefaction potential of granular soils. Understanding the fundamental mechanism underlying existing empirical or semi-empirical relationships is important for better assessing their reliability. This paper presents a particle-scale study of the correlation between cyclic resistance ratio (CRR) and the shear wave velocity corrected for overburden stress (V s1). The discrete-element method was used to simulate a series of undrained stress-controlled cyclic triaxial tests together with shear wave velocity (V s) measurements. Discrete-element method modelling with various relative densities, confining pressures and micro-parameters was performed under various cyclic stress ratios (CSRs), and the onset of liquefaction was illustrated through both macroscopic and microscopic responses, for example, inferred excess pore-water pressure, mechanical coordination number and redundancy index. The inter-particle friction was identified as the key micro-parameter that governs the liquefaction resistance of granular soils. A micro-scale CRR-V s1 correlation considering two independent micro-parameters, inter-particle friction and particle shear modulus, was then obtained and further validated with the outcomes from three dynamic centrifuge model tests performed on silica sand no. 8. This study demonstrates that the CRR-V s1 correlation is particle specific, thus soil specific, and the particle mechanical properties should be included in the V s-based method for future liquefaction evaluation of granular soils.

“…Near-surface shear wave velocity is of great importance in the fields of geophysics and earthquake engineering, since it is closely correlated with the physical and mechanical properties of soil and rock in shallow crust. In engineering practice, it has a wide range of applications, such as classification of building sites (Borcherdt, 1994), evaluation of liquefaction potential (Ahmadi & Paydar, 2014), estimation of seismic response (Choi & Stewart, 2005), and assessment of earthquake loss (Bendito et al, 2014). In recent years, shear wave velocity has been used to detect minor material changes in the subsurface for seismic monitoring of faults (Hillers & Campillo, 2018;Wegler & Sens-Schönfelder, 2007), volcanoes (Brenguier et al, 2014;Wegler et al, 2006), landslides (Bièvre et al, 2018;Mainsant et al, 2012), and hydrocarbon reservoirs (Bakulin & Calvert, 2006;Miyazawa et al, 2008).…”

We measured shear wave velocities in the shallow subsurface by applying seismic interferometry to earthquake records from eight vertical borehole arrays in eastern Hokkaido, Japan. We detected an increase of several percent in the seismic velocity during January to March due to seasonal frost dynamics. The velocity changes associated with seasonal frozen soil are affected by the frost depth and the extent of freezing, while the frost depth and the extent of freezing are mainly controlled by the cumulative temperature and the current temperature, respectively. Thus, a weighted cumulative freezing degree day is proposed to consider these two factors and used for stage division of the annual freeze‐thaw cycle. Based on the results of observation, we present an empirical model to relate the velocity changes with the weighted cumulative freezing degree days, which allows us to estimate the influence of seasonal frozen soil on near‐surface seismic velocity.

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.
