Abstract

Variations of soil associated with soil removal have been investigated in the Kamenoselandslide area. Its removal led to instability of the slope, as it was from the base of theslope. Both strain and inclination on the surface and internal strain showed remarkablechange, and the slope failure has occurred on Jan. 1st, 1967 and May 28th, 1967. The authoranalysed their variations as a process of creep rupture characteristics. The relationshipbetween the strain or the inclination and time in the tertiary creep range was used toforecast the time of occurrence of slope failure. It was shown that the analysis of thecompressive strain as well as the extensive strain was effective to forecast the time.
