Statistical Analysis of Failures of Constructed Embankment Dams
To study failures of constructed embankment dams, 1443 cases of failure of constructed embankment dams have been collected from the literature and compiled into a database. The embankment dams constructed during two periods, 1910‐1919 and 1960‐1969, appear to have suffered the highest rate of failure. This chapter discusses the breaching characteristics of embankment dams by overtopping and internal erosion. According to dam zoning, embankment dams can be classified into four categories as homogeneous earthfill dams, composite earthfill dams, earthfill dams with corewalls, and concrete faced earthfill dams. Homogeneous earthfill dams are composed of the same material. For the homogeneous earthfill dams and the composite earthfill dams, overtopping and internal erosion are two dominant failure causes. In contrast, for the earthfill dams with corewalls, failures are attributed to overtopping; internal erosion appears to be less common. It is evident from the comparison that the corewall plays a key role in preventing internal erosion in the dam.
