Abstract
Standard Penetration Test (SPT) and Cone Penetration Test (CPT) are widely used in geotechnical investi-gation methods for railway roadbed. However, SPT can not be used on the Railway track, since the equipment may con-tact to the electric lines. However, a portable equipment can be used for geotechnical investigation without electricalhazard. Dynamic Cone Penetrometer (DCP) is one of representative portable equipments. A normal portable DCP hasusually not enough driving energy and the rigidity of cone-rod, so it is impossible to investigate the required investigatepenetration depth. In this study, The adaptability of Pagani cone test which is one of portable dynamic cone penetrom-eter is studied and compared with SPT-N data. As a result of this study, the proposed correlation factors between Paganicone test and SPT-N values after corrections is 1.48 for sandy soil and 1.33 for clayey soil.
