Understanding the effect of a static driving shear stress on the liquefaction resistance of medium dense granular soils

New Insights in the Liquefaction Potential Evaluation Methods for Soils

“…These coefficients vary according to the soil nature and should be determined for each site if possible. The evaluations of K have been discussed [14]. Subsequently, K and K values were revised [15].…”

Liquefaction Mechanisms and Mitigation-A Review

“…The effect of initial static shear stresses and stressstrain relationship to analysis for a new nonlinear model with initial static shear stresses has been reported Akira and Hidetoshi (1986). There is also an explanation on soil mechanical properties investigation for definition static pre-shearing of medium dense granular soils and releasing static liquefaction resistance (Rahhal and Lefebvre, 2000). Static liquefaction in saturated loose sand has been discussed throughout the numerically modeling analysis based on alsoto-viscoplastic and nonlocal viscoplastic for evaluation of subsoil instability (Claudio and Silvia, 2002).…”

“…The static liquefaction mitigation of sandy subsoil has been made by several techniques, another example is sand reinforced with randomly distributing short polypropylene fiber (12 mm long) and experimental have been conducted using a ring-shear apparatus (DPRI-Ver.5) for assessing fiber effect on static liquefaction mitigation (Liu et al, 2011). These are several attempts (Akira and Hidetoshi, 1986;Rahhal and Lefebvre, 2000;Claudio and Silvia, 2002;Della et al, 2009;Ibraim et al, 2010;Liu et al, 2011) for liquefaction mitigation. But still many interpretations on liquefaction mitigation concept have been left.…”
