This paper presents evaluation and comparative analysis of liquefaction potential from Standard Penetration Test (SPT) and Cone Penetration Test (CPT) based deterministic relationships. Both methods have significant relative advantages, and can often be optimal when used in combinations. In this research, four pairs of SPT and CPT tests were carried out at the river bank of Jamuna, Bangladesh and each pair of test was conducted as close as possible. Particle size analysis on collected samples indicated that, fines content varied in the range of 3.5 to 39.2 percent. The recorded SPT N-values in different boreholes varied from 1 to 42 and maximum CPT resistance (q c) was approximately 20 MPa. It was observed that the recorded SPT N-value and CPT resistance considerably varied at some depths in certain locations. These result in some inconsistency in the safety factors against liquefaction calculated on the basis of SPT and CPT data. So, it is emphasized that quality test data is required to obtain consistent and reliable results when both methods are used in combinations for liquefaction analysis.
