Abstract

A variety of in-situ geotechnical investigation methods are currently used to measure the properties of each site, but in-situ tests for "Intermediate Geomaterial (IGM)", which is the transitional geomaterial between soil and rock, have only limited application. In the United States, "The Texas Cone Penetrometer Test (TCPT)", which is the geotechnical investigation technology for IGM, is utilized to create foundation designs. This paper introduces "The Driving Cone Penetrometer Test (DCPT)", which can be performed using general geotechnical investigation equipment and also analyzes the correlation between various in-situ geotechnical investigation methods by applying DCPT on the ground. The results showed that the correlation between the driving cone penetrometer test (DCPT) and standard penetration test (SPT) was quite high. Additionally, the scope of DCPT properties was wide, depending on soil types.
