Abstract
Structural strain responses of the jacket-type Uldolmok tidal current power plant structure under severe tidal environments were analyzed using long-term measurement data from construction to normal operation. From the measured data during construction, it was found that there were significant changes in strain responses at the steps of jacket lifting, weight-block loading, pile ejection and insertion. Strains due to permanent and tidal current loads were analyzed during removal work on one among six jacket legs, and it was found that the strains due to permanent load were much significantly changed after removal of on jacket leg. From the measurement data during normal operation, it was observed that strain responses were obviously fluctuated with M2 and M4 tidal periods and also with relatively short period of about 11 min due to the peculiar tidal characteristics in the Uldolmok strait.construction, it was found that there were significant changes in strain responses at the steps of jacket lifting, weight-block loading, pile ejection and insertion.
