Evaluation of Cyclic Resistance of Providence Silts Using Mini-Cone Penetration and Standard Penetration Tests
Most areas of coastal Rhode Island are underlain by thick layers of non-plastic silt and it is important to know if the existing standard-of-practice liquefaction potential evaluations (e.g. Robertson and Wride (1998) or Seed et al. (1985)) are accurate. The objective of this research was to critically evaluate the applicability of CPT and SPT based approaches to Providence silts. This was accomplished through a laboratory testing program involving the URI mini-cone calibration and cyclic triaxial tests to develop a new relationship between cyclic resistance ratio and the resistance for Providence silt. the new relationship was compared to the standard-of-practice liquefaction potential evaluation methods from the literature. There was good agreement between the approaches which shows that the existing field-based CPT methods are applicable to Rhode Island silts. This is consistent with previous RIDOT funded research on the liquefaction potential evaluation of silts in Rhode Island.
