Abstract
This study examines the variablity of Kunzelstab Penetration Test (KPT) results from site investigation on a fill slope soil from gap graded gravel with high plasticity silt. The principal uses of the KPT are examined surch as corretion method for N¢KPT, soil profile and allowable bearing capacity of soil foundation. KPT tests were conducted at 13 boreholes, each measuring 4 m long. Soil profile and allowable bearing capacity (Qa) along the holes were done using NKPT data. The number of blow count from KPT has been collected (N¢KPT) to obtain allowable bearing capacity. The result indicates the uncompacted layer and located the firm layer of soil foundation. The average allowable bearing capacity were 1.53 t/m2 and 17.06 t/m2 respectively. The study demonstrates the usefulness of the KPT method in geotechnical investigations, which is efficient, economic and less time consuming in comparison to the other geotechnical site investigation methods.
