Abstract

The Dynamic Cone Penetrometer (DCP) has been widely applied to estimate the subsurface characterizations by using penetration resistance. The objective of this study is to enlarge the application of DCP for detecting the active layer in freezing and thawing region. The Arctic area, located in Ny-Alseund, Svalbard, is selected to investigate the thickness of active layer through DCP. The experiment is started from surface to a depth of 800mm. The penetration depth according to every blow by impacting hammer is recorded. The three layers are divided by DCP and the thickness of active layer is investigated to the depth of 200mm through the minimum value of DCP. The thickness of active layer is also estimated by using the maximum ground temperature profile and the thickness of active layer based on the two methods show the good agreement. This study suggests that the DCP is useful instrument for investigating the thickness of active layer.
