Through the Tri-axial Cone Penetration Test (TCPT), the cone resistances in lab were obtained to compare and to correspond with those in field. Based on the soil investigation report of the reclaimed soils in Tai-Chung Harbor, two sets of Standard Penetration Test (SPT) and Cone Penetration Test (CPT) are selected to be the baseline data, and via TCPT, the cone resistances at each depth with corresponding relative density, fines content and effective confining pressures were acquired for a maximum depth of 20 m. The results indicate a reasonable agreement between the cone resistances obtained from TCPT and field CPT. Using this relationship, the cone resistances in lab were transformed to the ones in filed. Both the transformed cone resistances and actual ones were applied the liquefaction analyses of soils proposed by Robertson & Wride (1998) and Olsen(1997). The analysis results of safety factors in liquefaction resistance were presented and also discussed.
