土構造物における異種材料の適用(<小特集テーマ>土構造物の変化・変遷) Application of the Heterogeneous Material in the Earth Structures(Theme: Technological and Historical Changes of Earth Structure)
It is important to intend a harmony with a preservation of local environment and landscape in a design of earth structures. In the structures such as open cut and embankment structure, it is necessary to make efforts to minimize changes of geographical features by utilizing the natural lie of the land effectively. For this reason, the various types of embankment method with vertical wall have been developed up to the present.
