The current design procedure for an embankment constructed in a mountainous region does not take into account the influence rainfall run-off from the surrounding valleys in the quantitative determination of a safety factor. A number of road embankments in the mountainous areas of the Noto Peninsula failed due to the heavy rainfall in July, 1985. After site investigations were completed, it was found that those failures may have been triggered mainly by the rainfall run-off from the surrounding valleys. It is therefore considered unneglectable in a geotechnical engineering practice to introduce the degree of influence of rainfall run-off on the stability of embankments in mountainous regions. This paper describes a proposed design procedure for embankment in mountainous area making it possible to evaluate the safety factor considering the influence of rainfall run-off. In this proposed design method new indices are defined in order to quantitatively determine both the rate and amount of rainfall run-off. Thus proposed design procedure is effective to determine both the optimum safety factor against heavy rainfall for the embankments and the most appropriate countermeasures to be taken immediately, if necessary, for embankments already constructed. It is shown that this methodology is quite suitable and easy to apply from a practical engineering point of view.
