    RESEARCH STATUS AND PROSPECT OF THE STABILITY OF BARRIER DAM

    • At 14: 28,on 12 May 2008,the earthquake occurred at Richter scale 8.0 at Wenchuan county,Sichuan province and more than 30 barrier lakes came into being,which made a great threat on peoples life and property and drew great attention from all over the world. On the base of previous research,the paper summarizes the mechanism of forming and existence of barrier dams from topography and geomorphology,induced factors and lifetime. The focus is on the research progress of the stability of barrier dams. It is pointed out that the internal causes of the stability of barriers are morphology and scale,material composition and structure of barrier dams,and that the external causes is the volume of barrier lake. Then the paper summarizes the previous research results of key causes of the stability of barriers and of indoor model test. At last,the existing problems and future research direction of barrier dams is pointed out.
