Normally, the most methods of ground improvement of dike selected by evaluating economical efficiency, constructibility, and merits and demerit of methods simply. However, there are many factors to be considered such as environmental values, durability when selecting methods besides those factors. These factors have not been evaluated objectively but subjectively. The methods of construction depended on economical factor mainly. Therefore, this study is to select the best method of ground improvement of dike using AHP(Analytic Hierarchy Process) in Gunjang national industrial complex(Janghang site). As the results of this process, the very important factor is stable factor and the best method of construction is different by how to use AHP. Therefore, we recommend the advanced value evaluation to complement the process.
