Abstract
This paper presents the case study of a high embankment constructed by masa-soil (weathered granite rock) in granite district. In this study, a series of compression settlement and triaxial compression tests were performed to investigate the settlement properties, stress-strain relation and strength characteristics on the embankment material (masa-soil).
Test results shows that the compaction degree of the embankment more than DC=90% was effective for decreasing the settlement due to seepage, and the Mohr-Coulomb strength parameter of the embankment material was satisfied sufficiently with the design specification. The stability of high embankment slope was also estimated by the relation between the field observation results of embankment slope and the stress-strain curve of embankment material obtained by laboratory tests.
