000011191 520__ $$2eng$$aThe 2004 Mid Niigata Prefecture Earthquake which was one of the typical near-field earthquakes caused the serious damage to many kinds of road infrastructures in the mountainous areas. Especially, a large number of road embankments, which have been used popularly as road structures in the mountainous areas, suffered remarkable damage. Therefore, the aseismic countermeasures for improving the resistance of road embankment against earthquake are required to effectively preserve the road network even at an extreme earthquake. In this paper, two types of aseismic reinforcement techniques of road embankments are investigated in order to develop efficient and economical techniques for improving the resistance of road embankments against earthquake. Firstly, the numerical analytical, in which an elasto-plastic finite element analysis is applied, is proposed to calculate the resistance of road embankment against earthquake. In the analyses, the centrifuge model tests which were carried out to demonstrate experimentally the improvement of resistance of road embankments against earthquake is chosen as an analytical model. In the numerical analyses, the reinforcement area is chosen as a variable parameter. Finally, the availability of aseismic reinforcement techniques to the improving resistance against earthquake is discussed. Furthermore, the deformation characteristics of embankments, especially, location of sliding surface in the embankments are discussed, too.
