Seismic remediation for earth dams
- Geotechnical Lab., Vicksburgh, MS (United States). Army Engineer Waterways Experiment Station
There are hundreds of earth dams in the US, many of them old and some in need of seismic remediation to operate safely. This article is a look at the current state of the practice and at two US Army Corps of Engineers remediation projects now under way. Public safety demands that earth dams retain their reservoirs in an earthquake, or, at worst, release them without posing a threat to life. Dams have long been designed with this requirement in mind, but over the last 30 years or so, new analysis methods and case histories of dam performance in earthquakes have significantly changed the understanding of the severity of the earthquake hazard in many regions. Existing dams, especially older ones, are being reexamined using more severe earthquakes than their designers envisioned, with evaluation methods unavailable to them -- leading, in some cases, to the determination that a seismic hazard exists.
