콘크리트 중력식 댐의 동적 거동 특성 분석

초록

The purpose of this study is to suggest some references of maintenance and design of concrete gravity dams by analyzing dynamic characteristics in x,y,z directions. It is considered as additional mass,soil interaction for numerical dynamic analysis for gravity concrete dams in Han River basin as some areas. The result shows that the overflow structure can be possibly underestimated for the evaluation of the seismic performance using seismic intensity, modified seismic intensity methods. A much more research is still necessary for the evaluation of comprehensive seismic performance of concrete gravity dam.
