Site characterization is one of the most important performances in projects with regard to solving geotechnical problems. Piezocone penetration test is a fast, economic, and accurate method of site characterization. Static cone penetrometer and the piezocone represents the most versatile tools currently available for soil exploration. The cone penetration and piezocone tests provide continuous sounding capability and repeatability. Rare of consolidation parameter may be assessed form the Piezocone test by measuring the dissipation or decay of pore pressure with time after a stop in penetration. And many researches have been developed to determine the horizontal coefficent of consolidation from the Piezocone test. Many of these researches using a theoretical solutions which is determined from either the cavity expantion theory or the stress path method. However, depending on assumptions and analytical techniques, the results can be varied considerably. For that reason, many researchers make their effort to improve and complement the defect of already established methods. In this dissertation, the correlation between the Coefficient of Consolidation from Piezocone dissipation test and the Coefficient of Consolidation Rowe Cell horizontal consolidation test in many cases was studied. The purpose of this study is to know the changing of the Coefficient of Consolidation by loading condition while Rowe Cell horizontal consolidation test is used
