Abstract
This study conducted mini-cone penetration test in the Maoluo River soils of different fines contents under K0 condition with improved precision of the sleeve friction measurement. The effect of fines content on cone penetration resistance and sleeve friction resistance was studied and its relation with the liquefaction resistance of the soil obtained in the cyclic triaxial tests was also evaluated.
The test result show the normalized cone penetration resistance decreased with increasing fines content of the Maoluo river soils and the excess pore water pressure increased with increasing fines content of the Maoluo river soils.This study descries that the effects of the excess pore water pressure generation on mini cone penetration resistance and sleeve friction resistance.
The results of using the CPT-based liquefaction potential evaluation methods are not in good agreements with those of the laboratory test in this study. The reason maybe that the soils classification methods of the existing methods are not suitable for the local soils with high fines content in Taiwan.
