ON THE LONG-TERM STABILITY OF AN EMBANKMENT OF SOFT COHESIVE VOLCANIC SOIL

The study in this paper involves a stability analysis during and after the construction of a motorway embankment with the height of 20 M using volcanic cohesive soil called "Ashitaka loam". The soil is widely deposited around the southern foot of Mt Fuji and has high natural water content ranging from 120 to 230 percent. The strength of the soil decreases very sensitively with remolding actions during earthwork operations. Focus is placed in this paper on the deformation and settlement of an embankment and the variation of slope stability with the passage of time. All slope stability analyses were made by the effective stress method on the basis of in-place pore pressure measurements. (A) (TRRL)
