Study on Stability Evaluation of Concrete-Rockfill Combination Dam According to The Construction and Operation Stages

Abstract- It is important to evaluate scientifically stability of dam and embankment in large-scale hydropower construction, tideland construction and preventing natural disasters. The aim of paper is to establish a method of stability assessment of concrete-rockfill combination dam (CRCD) as a new dam form. In this paper, we investigated the step loads acting during construction, operation and seismic operation and their corresponding stability assessment methods for CRCDs. According to the results, the slope stability is also an important indicator for the stability evaluation of CRCDs and the stability assessment method of rockfill dams may be applied to the stability assessment of CRCDs.
