• This paper presents a new analysis method for designing rock-fill dams which are resistant to earthquakes; rock-fill dams mentioned in this paper are those consisting wholly of rock materials.When a rock-fill dam is subjected to a large earthquake force, it collapses, and the shape of the collapsing rock-fill dam approaches a circular arc in cross-section. The seismic coefficient circle method gives the relationship between the earthquake force, the cross-section of the circular arc and the stable cross-section formed in the circular arc at this moment.It is possible to obtain a seismic coefficient circle for any earthquake force (seismic coefficient) from theoretical considerations and thereby the cross-section of the dam required for any seismic coefficient can be designed.
