Design of new dams or safety evaluation of existing dams for seismic loads is standard practice and routinely required. In a broad term, dams can be classified into three types – concrete dam, rock-fill dam, and earthfill dam – and seismic design can be at a dam safety level and/or at a serviceability level.
This entry provides contents and discusses methods for design and analysis of earthfill dams at a dam safety level where the ultimate limit state is applied for the highest level of design earthquake loads. For dam safety, dam failure is the primary concern; for serviceability consideration, the dam should remain functional and any damages should be easily repairable under this level of earthquake loads.
