“…Accordingly, the number of cycles to liquefaction increases as the CSR decreases. This tendency is also observed in previous studies [3,4,7,21]. Regarding the effect of effective consolidation pressure, Wijewickreme et al [8] investigated the liquefaction resistance of tailing samples and revealed that the liquefaction resistance of laterite tailing samples tended to increase as the confining stress increased from 100 to 200 kPa.…”

“…The phenomenon of soil liquefaction has been widely investigated by different researchers, especially after the 1964 Niigata and Alaska earthquakes. In general, soil liquefaction resistance is affected by factors, such as soil type, fine content, grain characteristics, degree of saturation, relative density (void ratio), confining stress, cyclic loading frequency, and earthquake magnitude [2][3][4][5][6][7][8][9][10][11][12][13][14]. Recently, the soil liquefaction and the interaction between soil skeletion and pore fluid have been evaluated by using numerical modelling [15][16][17][18][19][20].…”

In the literature, the effect of different factors on the liquefaction resistance of sand has been widely investigated using the cyclic simple shear test or cyclic triaxial test. In which, the effect of CSR on liquefaction resistance significantly depends on the type of sand. In Vietnam, the sandy soils are widely distributed in coastal areas where many wind power farms are built and planned to build. Thus, the liquefaction resistance of sandy soil in these areas should be evaluated. In this study, the effect of cyclic stress ratio (CSR) on the liquefaction resistance of sand distributed in the coastal area of Soc Trang province, Vietnam will be evaluated for the first time using cyclic triaxial apparatus (Wykeham Farrance). The sand samples were prepared using the dry pluviation method with a relative density of about 56%. The stress-controlled method with CSR from approximately 0.1 to 0.35, the effective confining stress of 50 kPa, and the frequency of 1 Hz were applied. The research results showed that the axial strain and build-up of pore water pressure significantly depended on the range of CSR. In particular, this research has indicated the threshold of CSR for the liquefaction of sandy soil in this study area. Accordingly, under the testing conditions, sand samples were not liquefied with a CSR of less than 0.25.
