Abstract

It was performed that the stability evaluation using pseudo-static method and modified pseudo-static method for rockfill and rockfill-concrete section of composite dam. As a results of pseudo-static and modified pseudo-static analysis using seismic coefficient 0.154g, the maximum displacement at dam crest was occurred about 14~18cm on rockfill section and about 5~9cm on rockfill-concrete section, respectively. Also, that the factor of safety of down slope was more than 1.0~1.5. the rockfill and rockfill-concrete section of composite dam did not show any stability problems for 0.154g. Further research is still necessary in seismic safety of composite dam.
