From the viewpoints of soil engineering, geology, and slope disaster prevention engineering, field investigations were made of 109 failures of slopes with countermeasures such as sodding, retaining walls, and rock-fall prevention walls. Furthermore, physical properties and strength parameters of the surface soils were examined.The conclusions obtained are as follows: 1) In regard to the geology of Yamaguchi prefecture, the most slope failures occurred in the granite rock region. 2) Owing to the catchment topography, relatively small-scale failures occurred in slopes existing at the upper parts of the countermeasure works.
