Abstract
Embankments are constructed with compacting soil with the aim of improving their stability and deformation characteristics. In late years, increase of the torrential rain becomes the factor, and a lot of collapse examples of embankments are reported. Drainage measures for embankments against rainfall are different during construction and after commencement of use, and the effects are sustained intermittently from the start of construction to after the commencement of use. In this study, soil / water / air-coupled F.E. analysis of air dissolution type of embankments which take into account compaction and the history of rainfall/evaporation. Further, sudden torrential rain falls on the embankment after the commencement of use, and it aims to grasp how embankment destroys.
