## Abstract

In many parts of the world, especially in mountainous countries like Chile, Czechoslovakia, Iran, Italy, Japan, Mexico, Norway, Switzerland, and Yugoslavia, landslides are very common and have serious consequences for almost all construction activities in these countries. For example, over 9000 landslides were registered in Czechoslovakia during 1961–1962 (Zaruba and Mencl, 1969). In Japan over 2000 embankment failures occur on the average each year along the lines of the Japanese National Railways alone (Saito and Uezawa, 1969).
