Abstract
This study conducted mini-cone penetration test under K0 condition in a self-designed chamber with saturated Maoluo River sand samples of different fines content. The liquefaction resistances of soils with different fines content were also obtained using the CKC cyclic triaxial test apparatus. The effect of fines content on cone penetration resistance and sleeve friction resistance was studied and the relationship between cone penetration resistance, sleeve friction resistance and the liquefaction resistance of the soil was also evaluated.
According to the test results, normalized cone penetration resistance decreased with increasing fines content for soils of the same dry density and the vertical effective stress. Hence, we speculated the reason of fines content adjustment for cone penetration resistance in CPT-based liquefaction potential evaluation method was because the small liquefaction resistance changes while a more significant normalized cone penetration resistance decreasing with increasing fines content.
This study also shows the commonly used CPT-based liquefaction potential evaluation methods do not give good agreement with the findings in this study. The main reason is that that these methods do not have the suitable fines content adjustment for the local soils with high fines content in Taiwan.
