Abstract

The electrical resistivity methods have been commonly used for figuring out the ground layers. The purpose of this paper, differently from previous methods, is not only to figure out the layers but also to develope a equipment and a method to analyze ground porosity. Equipment has a shape of cone, which can be coupled with drilling rods. A field penetration test was performed to test application in Incheon Chungla area. Through the field test soil resistances were measured. To calculate soil porosity along the depth, Archie's law is applied. The results show that a new equipment and porosity analysis method using Archie's law can distinguish soil layers and precisely measure soil porosity.
