Abstract
The filldams are one of the oldest infrastructures in Japan having 1,400 year history and contributing to supply of irrigation and municipalwater,hydropower generation and flood control. AfterWorldWar II, especially after 1960's, the height and volume of dams increased dramatically with the growth of national economy to pursue the scale merits. In this paper, the development of construction capability is presented with special emphasis on hauling capacity. Compaction equipment and its quality control are also discussed which arevery much related to the strength and deformation properties of earthfill and rockfill. The design considerations are reviewed on the slope stability, seepage control and design flood of spillway. Based on these discussions, the proposals and research topics are given on the design and construction to develop embankment engineering further.
