| Outline of Final Research Achievements |
In order to maintain the long-term safety operation of the practical use Tainter gates, theoretical and experimental studies were conducted. First, the operational dynamic stability were secured by using the previous field test results and our theoretical analysis. Second, the countermeasure and reinforcement, such as installation of damper and additional mass for the skinplate structure were examined by theoretical and FEM analysis. In addition, the flexible wire cables of the gate to ensure the safety, were examined its validity in model experiments. Moreover, the safety operating range with small gate opening were expanded after confirmation of the long-term dynamic stability from the field vibration test for practical use Tainter gate.
