DEFORMATION BEHAVIOR AND STABILITY OF HIGH EMBANKMENT SLOPE CONSTRUCTED AT STEEP-VALLEY (RIVER TERRACE DISTRICT)

Abstract

This paper presents the case study of a high embankment with the maximum height of about 90m consaucted by coarse-grained soil (weathered conglomerate rock with mudstone or sandstone) in river terrace district.
A series of compression settlement tests and triaxial compression tests were performed to investigate the settlement properties, stress-strain relation and strength characteristics on the embankment material. The field observation results of deformation and slope stability analysis of the embankment under construction was also described. The stability of high embankment slope was also evaluated from the relation between the observed deformation of embankment slope and the stress-strain curve of embankment material obtained by laboratory tests.
