This study aimed to examine the failure mechanisms of the Fujinuma Dam and introduce possible seismic strengthening methods for earth dams. The study consists of field and laboratory experiments and a numerical simulation of the dam. Laboratory experiments were conducted to acquire necessary information. For the seismic analysis, a coupled solid-fluid finite element formulation was applied. The observed and simulated motions of the 2011 Tohoku Earthquake were used as input motions. Frequency and dynamic analyses were performed thereafter; dam behavior and possible failure mechanisms are presented. In addition, the seismic strengthening techniques of the studied dam are introduced and discussed.
