碩士 / 國立臺灣海洋大學 / 河海工程學系 / 93 / The main purpose of this thesis is to investigate a special configuration of a thin offshore breakwater, which is situated in a constant depth of water and in front of a vertical wall at the straight shoreline. In this configuration of the breakwater and neglecting energy loss, it will be nearly no effects on the normally incident wave trains. We call this situation as the “failure configuration”. Based on the standing wave theory, the failure situation may be predicted and illustrated. To verify our prediction, ten types of configuration of the thin offshore breakwater (single one, two collinear, two parallel, two staggered, one perpendicular, L-shaped, Γ-shaped, U-shaped, and ㄇ-shaped offshore breakwater) have been calculated by the boundary element program in this thesis. Our prediction, this configuration will be failure in case of a thin offshore breakwater sited at the loops of standing waves, is confirmed by the numerical results. The expected function of the offshore breakwater will be lost and the engineering cost will be wasted in the failure configuration. Therefore, the achievements of this thesis could keep engineers away from such bad situations and offer some references for harbor and coastal engineering.
