摘要: A dam may fail when the loading exceeds resistance against overtopping, internal erosion, slope instability, sliding/overturning, excessive deformation etc. To investigate causes of failures, it is necessary to study characteristics dams which have experienced failures. In this work, more than 1600 failure cases throughout world excluding China are compiled into a database, including details dams, reservoirs, triggers and This paper focuses on earth make up 66% in database. statistical analysis conducted. According zoning corewalls, divided four typical categories: homogeneous earthfill zoned with concrete faced dams. Further modes types carried out. Potential locations at risk also described provide reader...
