摘要：

This paper discusses the general liquefaction state of unsaturated soil related to the mudflow type slope failures observed during earthquakes in areas covered with volcanic ash sand deposits. It is found that the volume compressibility of soil structure, the degree of saturation and the confining pressure are key factors governing the liquefaction of unsaturated soils.
