並列タイトル等Breakwater Damage and the Effect of Breakwaters on Mitigation of Inundation Extent During Tsunamis: Case Study of The 2011 Great East Japan Earthquake and Tsunami
タイトル(掲載誌)Handbook of Coastal Disaster Mitigation for Engineers and Planners
一般注記Given the importance of ports for immediate disaster relief operations after a major tsunami takes place, breakwaters are necessary to sustain at least a minimum level of the functionality necessary for facilitating port operations. However, most breakwaters protecting fishery ports or industrial ports are not designed against the possibility of a tsunami attack. As a result, many of these breakwaters were destroyed by The 2011 Great East Japan Earthquake and Tsunami. On the other hand, some breakwaters endured the tsunami, facilitating the rapid resumption of port operations. This chapter investigates what percentage of breakwaters suffered failures due to the 2011 Tsunami, and how tsunami height influenced the degree of breakwater failure. Also, the effectiveness of conventional breakwaters in mitigating tsunami attack has not been sufficiently investigated in the past, and thus the authors also carried out an investigation to ascertain to what degree such breakwaters can mitigate tsunami inundation behind them.
